Description: High-availability support for PostgreSQL logical replication
 This extension is for anyone with Logical Replication Slots on
 Postgres databases that are also part of a Physical Streaming
 Replication architecture.
 .
 Since logical replication slots are only maintained on the primary
 node, downstream subscribers don't receive any new changes from a
 newly promoted primary until the slot is created, which is unsafe
 because the information that includes which data a subscriber has
 confirmed receiving and which log data still needs to be retained for
 the subscriber will have been lost, resulting in an unknown gap in
 data changes. PG Failover Slots makes logical replication slots
 usable across a physical failover using the following features:
 .
  - Copies any missing replication slots from the primary to the
    standby
  - Removes any slots from the standby that aren't found on the primary
  - Periodically synchronizes the position of slots on the standby
    based on the primary
  - Ensures that selected standbys receive data before any of the
    logical slot walsenders can send data to consumers
