- Fixed critical bug where ALTER SYSTEM + pg_reload_conf() was used
but max_locks_per_transaction requires a full PostgreSQL restart
- Added automatic restart attempt (systemctl, service, pg_ctl)
- Added loud warnings if restart fails with manual fix instructions
- Updated preflight checks to warn about low max_locks_per_transaction
- This was causing 'out of shared memory' errors on BLOB-heavy restores
- Visual progress bars for cloud uploads/downloads
- Byte transfer display, speed, ETA prediction
- Color-coded Unicode block progress
- Checksum verification with progress bar for large files
- Spinner for indeterminate operations (unknown size)
- New types: NewSchollzBar(), NewSchollzBarItems(), NewSchollzSpinner()
- Progress Writer() method for io.Copy integration
- Added gopsutil/v3 for cross-platform system metrics
* Works on Linux, macOS, Windows, BSD
* Memory detection no longer requires /proc parsing
- Added go-humanize for readable output
* humanize.Bytes() for memory sizes
* humanize.Comma() for large numbers
- Improved preflight display with memory usage percentage
- Linux kernel checks (shmmax/shmall) still use /proc for accuracy
- Linux system checks (read-only from /proc, no auth needed):
* shmmax, shmall kernel limits
* Available RAM check
- PostgreSQL auto-tuning:
* max_locks_per_transaction scaled by BLOB count
* maintenance_work_mem boosted to 2GB for faster indexes
* All settings auto-reset after restore (even on failure)
- Archive analysis:
* Count BLOBs per database (pg_restore -l or zgrep)
* Scale lock boost: 2048 (default) → 4096/8192/16384 based on count
- Nice TUI preflight summary display with ✓/⚠ indicators
