Re: Minimal logical decoding on standbys

Even after calling pg_logical_slot_get_changes() multiple times? What
does
SELECT * FROM pg_replication_slots; before and after multiple calls return?

Does manually forcing a checkpoint with CHECKPOINT; first on the primary
and then the standby "fix" the issue?

Yes,eventually it gets clean up -after firing multiple times get_changes function or checkpoint or even both.
This same behavior we are able to see  on MASTER  -with or without patch.

but is this an old (existing) issue ?

b)pg_wal files are not recycling  and every time it is creating new files
after firing get_changes function

I'm not sure what you mean by this. Are you saying that
pg_logical_slot_get_changes() causes WAL to be written?

No, when i said - created new WAL files , i meant -after each pg_bench run NOT after executing  get_changes.
