I think if we want to follow
this approach then we need to also monitor these slots for any change
in the consecutive cycles and if we are able to sync them then
accordingly we enable them to use after failover.
What about to add a new field in ReplicationSlotPersistentData
indicating that we are waiting for "sync" and drop such slots during promotion
and
/or if not in recovery?
This patch is already adding 'synced' flag in
ReplicationSlotPersistentData to distinguish synced slots so that we
can disallow decoding on then in standby and disallow to drop those. I
suggest we change that field to have multiple states where one of the
states would indicate that the initial sync of the slot is done.
Yeah, agree.
