Mastering PostgreSQL Performance with Vacuum

PostgreSQL is a favorite database among Laravel developers, but high-write workloads can lead to dead tuple accumulation, unindexed foreign keys, and table bloat that degrades query performance. Vacuum is a purpose-built package for monitoring and tuning PostgreSQL databases inside Laravel applications.

What Vacuum Checks

• Dead Tuple & Table Bloat: Monitors table fragmentation and alerts when autovacuum routines fail to keep pace with record updates.
• Missing Foreign Key Indexes: Identifies unindexed relation columns that trigger table-wide sequential scans during cascade operations.
• Transaction ID Wraparound: Keeps track of database transaction age to prevent catastrophic database shutdown states.
• Unused & Duplicate Indexes: Recommends obsolete indexes that consume write throughput and disk cache without improving query plans.

CLI Command Example

# Run complete PostgreSQL health audit
php artisan vacuum:check

# Inspect bloat on specific table
php artisan vacuum:bloat users
