698b8a761c feat(restore): add weighted progress, pre-extraction disk check, parallel-dbs flag
All checks were successful
CI/CD / Test (push) Successful in 1m20s
CI/CD / Lint (push) Successful in 1m32s
CI/CD / Build & Release (push) Successful in 3m19s
Three high-value improvements for cluster restore:

1. Weighted progress by database size
   - Progress now shows percentage by data volume, not just count
   - Phase 3/3: Databases (2/7) - 45.2% by size
   - Gives more accurate ETA for clusters with varied DB sizes

2. Pre-extraction disk space check
   - Checks workdir has 3x archive size before extraction
   - Prevents partial extraction failures when disk fills mid-way
   - Clear error message with required vs available GB

3. --parallel-dbs flag for concurrent restores
   - dbbackup restore cluster archive.tar.gz --parallel-dbs=4
   - Overrides CLUSTER_PARALLELISM config setting
   - Set to 1 for sequential restore (safest for large objects)

dd7c4da0eb fix(restore): add 100ms delay between database restores
All checks were successful
CI/CD / Test (push) Successful in 1m19s
CI/CD / Lint (push) Successful in 1m27s
CI/CD / Build & Release (push) Successful in 3m17s
Ensures PostgreSQL fully closes connections before starting next
restore, preventing potential connection pool exhaustion during
rapid sequential cluster restores.

b2a78cad2a fix(dedup): use deterministic seed in TestChunker_ShiftedData
Some checks failed
CI/CD / Test (push) Successful in 1m18s
CI/CD / Lint (push) Successful in 1m27s
CI/CD / Build & Release (push) Has been cancelled
The test was flaky because it used crypto/rand for random data,
causing non-deterministic chunk boundaries. With small sample sizes
(100KB / 8KB avg = ~12 chunks), variance was high - sometimes only
42.9% overlap instead of expected >50%.

Fixed by using math/rand with seed 42 for reproducible test results.
Now consistently achieves 91.7% overlap (11/12 chunks).

5728b465e6 fix(tui): handle tea.InterruptMsg for proper Ctrl+C cancellation
Some checks failed
CI/CD / Lint (push) Successful in 1m30s
CI/CD / Build & Release (push) Has been skipped
CI/CD / Test (push) Failing after 1m16s
Bubbletea v1.3+ sends InterruptMsg for SIGINT signals instead of
KeyMsg with 'ctrl+c', causing cancellation to not work properly.

- Add tea.InterruptMsg handling to restore_exec.go
- Add tea.InterruptMsg handling to backup_exec.go
- Add tea.InterruptMsg handling to menu.go
- Call cleanup.KillOrphanedProcesses on all interrupt paths
- No zombie pg_dump/pg_restore/gzip processes left behind

Fixes Ctrl+C not working during cluster restore/backup operations.

Critical PostgreSQL-specific fixes identified by database expert review:

1. **Port always passed for localhost** (pg_dump, pg_restore, pg_dumpall, psql)
   - Previously, port was only passed for non-localhost connections
   - If user has PostgreSQL on non-standard port (e.g., 5433), commands
     would connect to wrong instance or fail
   - Now always passes -p PORT to all PostgreSQL tools

2. **CREATE DATABASE with encoding/locale preservation**
   - Now creates databases with explicit ENCODING 'UTF8'
   - Detects server's LC_COLLATE and uses it for new databases
   - Prevents encoding mismatch errors during restore
   - Falls back to simple CREATE if encoding fails (older PG versions)

3. **DROP DATABASE WITH (FORCE) for PostgreSQL 13+**
   - Uses new WITH (FORCE) option to atomically terminate connections
   - Prevents race condition where new connections are established
   - Falls back to standard DROP for PostgreSQL < 13
   - Also revokes CONNECT privilege before drop attempt

4. **Improved globals restore error handling**
   - Distinguishes between FATAL errors (real problems) and regular
     ERROR messages (like 'role already exists' which is expected)
   - Only fails on FATAL errors or psql command failures
   - Logs error count summary for visibility

5. **Better error classification in restore logs**
   - Separate log levels for FATAL vs ERROR
   - Debug-level logging for 'already exists' errors (expected)
   - Error count tracking to avoid log spam

These fixes improve reliability for enterprise PostgreSQL deployments
with non-standard configurations and existing data.

9d95a193db Fix: Enterprise cluster restore (postgres user via su)
All checks were successful
CI/CD / Test (push) Successful in 1m16s
CI/CD / Lint (push) Successful in 1m29s
CI/CD / Build & Release (push) Successful in 3m13s
Critical fixes for enterprise environments where dbbackup runs as
postgres user via 'su postgres' without sudo access:

1. canRestartPostgreSQL(): New function that detects if we can restart
   PostgreSQL. Returns false immediately if running as postgres user
   without sudo access, avoiding wasted time and potential hangs.

2. tryRestartPostgreSQL(): Now calls canRestartPostgreSQL() first to
   skip restart attempts in restricted environments.

3. Changed restart warning from ERROR to WARN level - it's expected
   behavior in enterprise environments, not an error.

4. Context cancellation check: Goroutines now check ctx.Err() before
   starting and properly count cancelled databases as failures.

5. Goroutine accounting: After wg.Wait(), verify all databases were
   accounted for (success + fail = total). Catches goroutine crashes
   or deadlocks.

6. Port argument fix: Always pass -p port to psql for localhost
   restores, fixing non-standard port configurations.

This should fix the issue where cluster restore showed success but
0 databases were actually restored when running on enterprise systems.

3201f0fb6a Fix: Critical bug - cluster restore showing success with 0 databases restored
All checks were successful
CI/CD / Test (push) Successful in 1m14s
CI/CD / Lint (push) Successful in 1m25s
CI/CD / Build & Release (push) Successful in 3m23s
CRITICAL FIXES:
- Add check for successCount == 0 to properly fail when no databases restored
- Fix tryRestartPostgreSQL to use non-interactive sudo (-n flag)
- Add 10-second timeout per restart attempt to prevent blocking
- Try pg_ctl directly for postgres user (no sudo needed)
- Set stdin to nil to prevent sudo from waiting for password input

This fixes the issue where cluster restore showed success but no databases
were actually restored due to sudo blocking on password prompts.

The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/),
and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).
## [3.42.50] - 2026-01-16 "Ctrl+C Signal Handling Fix"
### Fixed - Proper Ctrl+C/SIGINT Handling in TUI
- **Added tea.InterruptMsg handling** - Bubbletea v1.3+ sends `InterruptMsg` for SIGINT signals
instead of a `KeyMsg` with "ctrl+c", causing cancellation to not work
- **Fixed cluster restore cancellation** - Ctrl+C now properly cancels running restore operations
- **Fixed cluster backup cancellation** - Ctrl+C now properly cancels running backup operations
- **Added interrupt handling to main menu** - Proper cleanup on SIGINT from menu
- **Orphaned process cleanup** - `cleanup.KillOrphanedProcesses()` called on all interrupt paths
### Changed
- All TUI execution views now handle both `tea.KeyMsg` ("ctrl+c") and `tea.InterruptMsg`
- Context cancellation properly propagates to child processes via `exec.CommandContext`
- No zombie pg_dump/pg_restore/gzip processes left behind on cancellation
## [3.42.49] - 2026-01-16 "Unified Cluster Backup Progress"
### Added - Unified Progress Display for Cluster Backup
- **Combined overall progress bar** for cluster backup showing all phases:
- Phase 1/3: Backing up Globals (0-15% of overall)
- Phase 2/3: Backing up Databases (15-90% of overall)
- Phase 3/3: Compressing Archive (90-100% of overall)
- **Current database indicator** - Shows which database is currently being backed up
- **Phase-aware progress tracking** - New fields in backup progress state:
- `overallPhase` - Current phase (1=globals, 2=databases, 3=compressing)
- `phaseDesc` - Human-readable phase description
- **Dual progress bars** for cluster backup:
- Overall progress bar showing combined operation progress
- Database count progress bar showing individual database progress
### Changed
- Cluster backup TUI now shows unified progress display matching restore
- Progress callbacks now include phase information
- Better visual feedback during entire cluster backup operation
## [3.42.48] - 2026-01-15 "Unified Cluster Restore Progress"
### Added - Unified Progress Display for Cluster Restore
- **Combined overall progress bar** showing progress across all restore phases:
- Phase 1/3: Extracting Archive (0-60% of overall)
- Phase 2/3: Restoring Globals (60-65% of overall)
- Phase 3/3: Restoring Databases (65-100% of overall)
- **Current database indicator** - Shows which database is currently being restored
- **Phase-aware progress tracking** - New fields in progress state:
- `overallPhase` - Current phase (1=extraction, 2=globals, 3=databases)
- `currentDB` - Name of database currently being restored
- `extractionDone` - Boolean flag for phase transition
- **Dual progress bars** for cluster restore:
- Overall progress bar showing combined operation progress
- Phase-specific progress bar (extraction bytes or database count)
### Changed
- Cluster restore TUI now shows unified progress display
- Progress callbacks now set phase and current database information
- Extraction completion triggers automatic transition to globals phase
- Database restore phase shows current database name with spinner
### Improved
- Better visual feedback during entire cluster restore operation
- Clear phase indicators help users understand restore progress
- Overall progress percentage gives better time estimates
## [3.42.35] - 2026-01-15 "TUI Detailed Progress"
### Added - Enhanced TUI Progress Display
- **Detailed progress bar in TUI restore** - schollz-style progress bar with:
- Byte progress display (e.g., `245 MB / 1.2 GB`)
- Transfer speed calculation (e.g., `45 MB/s`)
- ETA prediction for long operations
- Unicode block-based visual bar
- **Real-time extraction progress** - Archive extraction now reports actual bytes processed
- **Go-native tar extraction** - Uses Go's `archive/tar` + `compress/gzip` when progress callback is set
- **New `DetailedProgress` component** in TUI package:
- `NewDetailedProgress(total, description)` - Byte-based progress
- `NewDetailedProgressItems(total, description)` - Item count progress
- `NewDetailedProgressSpinner(description)` - Indeterminate spinner
- `RenderProgressBar(width)` - Generate schollz-style output
- **Progress callback API** in restore engine:
- `SetProgressCallback(func(current, total int64, description string))`
- Allows TUI to receive real-time progress updates from restore operations
- **Shared progress state** pattern for Bubble Tea integration
### Changed
- TUI restore execution now shows detailed byte progress during archive extraction
- Cluster restore shows extraction progress instead of just spinner
- Falls back to shell `tar` command when no progress callback is set (faster)
### Technical Details
- `progressReader` wrapper tracks bytes read through gzip/tar pipeline
- Throttled progress updates (every 100ms) to avoid UI flooding
- Thread-safe shared state pattern for cross-goroutine progress updates
## [3.42.34] - 2026-01-14 "Filesystem Abstraction"
### Added - spf13/afero for Filesystem Abstraction
