[GENERAL] wal_retrieve_retry_interval

Hi,

Say, with 9.6.2,  a hot_standby fails to connect to a replication slot:

    FATAL:  could not start WAL streaming: ERROR:  replication slot "test3" does not exist

or

    FATAL:  could not connect to the primary server: FATAL:  the database system is starting up

Is there a way to reduce the time it takes until the next attempt? I assumed, wrongly I think, that this would be wal_retrieve_retry_interval, but it seems that it won't make a difference. I tried setting it to 3s, but it seems to take 15s still. Here are two log samples:

1.
