Pgcli and Rsync: Precision Tools for Fast, Reliable PostgreSQL Operations

You opened a terminal and reached for two tools that never fail: pgcli and rsync. Together, they turn chaos into control.

pgcli is a command-line client for PostgreSQL with auto-completion and syntax highlighting. It makes querying faster, reduces typos, and helps you see results without wasting keystrokes. When managing large databases, speed at the keyboard is speed in production.

rsync moves data fast and intelligently. It copies only the parts of a file that change, using compression and network efficiency to keep transfers lean. For PostgreSQL workflows, rsync is battle-tested for moving backups, synchronizing replica data directories, and restoring systems without blocking the main database for hours.

Here’s a simple, safe approach to pair pgcli with rsync for PostgreSQL operations:

1. Use pgcli to verify connections and run SELECT pg_start_backup() on the primary.
2. Run rsync -az --progress /var/lib/postgresql/12/main user@replica:/var/lib/postgresql/12/main to copy the data directory.
3. Return to pgcli and run SELECT pg_stop_backup().
4. Start the replica and confirm synchronization with a quick query from pgcli on both nodes.

This workflow is predictable, fast, and easy to automate. You get the elegance of pgcli’s interface combined with the raw efficiency of rsync’s data transfer. It works for snapshotting before migrations, preparing standby replicas, or moving datasets between environments.

When the database drives the business, you cannot afford downtime or data drift. pgcli and rsync give you precision under pressure.
