PostgreSQL logical replication Terraform provider

A Terraform provider for managing PostgreSQL logical replication slots.

Summary

Manages the lifecycle of logical replication slots. It is useful to manage the lifecycle of replication slots outside of the service that is consuming them. If the service is shut down you probably want the slot to stay alive so you can resume streaming when the service is started up again, it is only if a service is decommissioned that you want the slot to be removed. By defining the slot independently from the service lifecycle you can clean up the slot when the application is no longer needed.
