Hi PostgreSQL community, I am investigating a problem with a backend that appears to be stuck and spinning while performing a "DISCARD ALL" command. The system is running an older release 9.2.2. Are there any bugs that could be causing this behavior? How can I tell what the process is actually doing? It does not respond to either pg_cancel_backend() or to pg_terminate_backend() so it is acting like it is not receiving the signals. Any ideas on how to debug this would be appriciated.
What does the Postgres log show around the time of the command and/or currently?
What OS and does it's system log show anything? Can you query pg_stat_activity? http://www.postgresql.org/docs/9.2/static/monitoring-stats.html#PG-STAT-ACTIVITY-VIEW
