Database Connection Issues

Troubleshoot database connectivity problems.

PostgreSQL Connection Refused​

Symptom: ECONNREFUSED 127.0.0.1:5432

Fixes:

  1. Check PostgreSQL is running: pg_isready
  2. Verify DB_HOST and DB_PORT in .env
  3. Check PostgreSQL pg_hba.conf allows connections

Authentication Failed​

Symptom: password authentication failed for user

Fixes:

  1. Verify DB_USER and DB_PASS in .env
  2. Check user exists: \du in psql
  3. Reset password: ALTER USER gauzy WITH PASSWORD 'new-password';

SSL Required​

Symptom: no pg_hba.conf entry for host ... SSL off

Fix: Set SSL mode:

DB_SSL_MODE=true

Connection Pool Exhausted​

Symptom: too many clients already or slow queries

Fixes:

  1. Increase pool size: DB_POOL_SIZE=60
  2. Use PgBouncer for connection pooling
  3. Check for connection leaks (unclosed connections)

Migration Errors​

Symptom: relation "xxx" does not exist

Fix:

# Run pending migrations
yarn typeorm migration:run

# Check migration status
yarn typeorm migration:show

SQLite Lock Errors​

Symptom: SQLITE_BUSY: database is locked

Fix: SQLite doesn't support concurrent writes. For multi-user, switch to PostgreSQL:

DB_TYPE=postgres
