PostgreSQL Tuning and Operations
What it does
Tunes, designs, and operates PostgreSQL: slow queries, indexes, schemas, migrations, vacuum, locks, replication, backups. Use when writing Postgres SQL or psql, designing tables and indexes, reading an EXPLAIN plan, running DDL or a migration against a live table, or when a query suddenly got slow, a table keeps growing while rows stay flat, autovacuum cannot keep up, "too many clients already" appears, a replica lags, deadlocks and lock waits pile up, pg_wal fills the disk, or an upgrade, a restore, or a partitioning plan is on the table. Covers connection pooling and PgBouncer, full-text, trigram and pgvector search, JSONB, roles and row-level security, PITR, extensions, and managed Postgres (RDS, Aurora, Cloud SQL, Neon, Supabase). Not for cross-engine SQL portability or ORM-level modeling.
