Re: allow online change primary_conninfo

Hello

"Waiting on Author" is the right status. I found logical conflict with recently added wal_receiver_create_temp_slot GUC
andmy tests are currently broken. Will fix it and post new version.
 

PS: also, I surprised why it's ok for wal_receiver_create_temp_slot to be PGC_SIGHUP and ignore change of this setting
untilwalreceiver will reconnect by unrelated reason. I means walreceiver does nothing special on SIGHUP. In common case
changeof wal_receiver_create_temp_slot setting will have effect only during restart of walreceiver process. And
thereforewe will switch to archive recovery. But such design was strongly rejected for my patch year ago.
 

regards, Sergei
