Phase 1: Detection & Guidance
- Detect OS user vs DB user mismatch
- Identify PostgreSQL authentication method (peer/ident/md5)
- Show helpful error messages with 4 solutions:
1. sudo -u <user> (for peer auth)
2. ~/.pgpass file (recommended)
3. PGPASSWORD env variable
4. --password flag
Phase 2: pgpass Support
- Auto-load passwords from ~/.pgpass file
- Support standard PostgreSQL pgpass format
- Check file permissions (must be 0600)
- Support wildcard matching (host:port:db:user:pass)
Tested on CentOS Stream 10 with PostgreSQL 16
HIGH PRIORITY FIXES:
1. Remove unused progressCallback mechanism (dead code cleanup)
2. Add unit tests for restore package (formats, safety checks)
- Test coverage for archive format detection
- Test coverage for safety validation
- Added NullLogger for testing
3. Fix ignored errors in backup pipeline
- Handle StdoutPipe() errors properly
- Log stderr pipe errors
- Document CPU detection errors
IMPROVEMENTS:
- formats_test.go: 8 test functions, all passing
- safety_test.go: 6 test functions for validation
- logger/null.go: Test helper for unit tests
- Proper error handling in streaming compression
- Fixed indentation in stderr handling
- PostgreSQL and MySQL support
- Interactive TUI with fixed menu navigation
- Line-by-line progress display
- CPU-aware parallel processing
- Cross-platform build support
- Configuration settings menu
- Silent mode for TUI operations
