After going over this a bunch more times, I found other problems. For example, I noticed that if I create a temporary slot in one session, then another session would rightly go to sleep if it tries to drop that slot. But the slot goes away when the first session disconnects, so I'd expect the sleeping session to get a signal and wake up, but that doesn't happen.
I'm going to continue to look at this and report back Tuesday 18th. -- Álvaro Herrera https://www.2ndQuadrant.com/ PostgreSQL Development, 24x7 Support, Remote DBA, Training & Services -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
