What Is Replication Slots in Postgres?

Replication slots in Postgres are a feature that allows you to more finely control the replication process, and can be used to avoid issues with the replication process stalling or failing.

When setting up replication, you can create one or more replication slots on the master server. These act as a buffer for the WAL (write-ahead log) data that is being sent from the master to the replica.

If the replica falls behind for any reason, the replication slot will ensure that the WAL data is not lost and can be replayed when the replica catches up.

This is especially useful in cases where the replica is taken offline for maintenance or upgrades, as it can simply replay the WAL data from the replication slot when it comes back online.

In short, replication slots provide a way to ensure that your replica stays up to date, even if it falls behind for a period of time.
