Pgcli is more than a Postgres command-line tool with auto-completion and syntax highlighting. It’s often a gateway to critical data. Without strict password rotation policies, that gateway stays open longer than it should. One breached account can linger in your system. Each rotation cuts off the lingering access.
A strong password rotation policy for Pgcli starts with the source: the Postgres configuration. Store credentials outside the tool itself, preferably in environment variables or .pgpass files with locked-down file permissions. The rotation process should update these credentials automatically, not manually, to avoid human delay. Scripts built into your CI/CD pipeline or scheduled jobs in your infrastructure can force Pgcli connections to fail until updated with the new credentials.
Frequency matters. Monthly or quarterly rotations keep the attack window small. Match this interval to your risk profile and compliance needs. Pair rotations with unique passwords per environment—production, staging, and development—so a leaked dev credential never opens prod. Always use generated passwords from a secure password manager or secrets management system, not patterns or reused sequences.
