Hi, I have created my own output plugin for logical decoding. I am storing decoded data in Apache kafka via pg_recvlogical utility. Using pg_recvlogical I am updating confirmed_flush_lsn of slot based on the value that I'm storing in kafka,this is done for every 10 secs.
In case of walsender shutdown I found that canditate_restart_lsn is not cleared from shared memory.I also found just after restarting sometimes canditate_restart_lsn is far more greater than actual restart_lsn of slot,due to this frequent checkpoints are deleting the required WAL files. Can I clear the canditate_restart_lsn in plugin_start callback.Is there any consequences for this? Thanks and Regards, G R MANJUNATH.
