Thread: pgsql: Ignore recovery_min_apply_delay until recovery has reached consi
Ignore recovery_min_apply_delay until recovery has reached consistent state Previously recovery_min_apply_delay was applied even before recovery had reached consistency. This could cause us to wait a long time unexpectedly for read-only connections to be allowed. It's problematic because the standby was useless during that wait time. This patch changes recovery_min_apply_delay so that it's applied once the database has reached the consistent state. That is, even if the delay is set, the standby tries to replay WAL records as fast as possible until it has reached consistency.
