- Created internal/cleanup package for orphaned process management
- KillOrphanedProcesses(): Finds and kills pg_dump, pg_restore, gzip, pigz
- killProcessGroup(): Kills entire process groups (handles pipelines)
- Pass parent context through all TUI operations (backup/restore inherit cancellation)
- Menu cancel now kills all child processes before exit
- Fixed context chain: menu.ctx → backup/restore operations
- No more zombie processes when user quits TUI mid-operation
Context chain:
- signal.NotifyContext in main.go → menu.ctx
- menu.ctx → backup_exec.ctx, restore_exec.ctx
- Child contexts inherit cancellation via context.WithTimeout(parentCtx)
- All exec.CommandContext use proper parent context
Prevents: Orphaned pg_dump/pg_restore eating CPU/disk after TUI quit
- Auto-detects existing user databases before cluster restore
- Shows count and list (first 5) in preview screen
- Toggle option 'c' to enable cluster cleanup
- Drops all user databases before restore when enabled
- Works for PostgreSQL, MySQL, MariaDB
- Safety warning with database count
- Implements practical disaster recovery workflow
- Cluster restores restore multiple databases, not a single target
- Database existence check was failing with exit status 2
- Now shows "Will restore all databases from cluster backup" instead
- Removes confusing warning for cluster restore operations
