We did a pg_upgrade from 9.5 to 9.6 Now, when running the 9.6 server the following error message shows up regularly in the log:
postgres@template1 ERROR: column "waiting" does not exist at character 217 As far as I understand the following remark in the release notes, the column 'waiting' should not exist: - Improve the pg_stat_activity <https://www.postgresql.org/docs/9.6/static/monitoring-stats.html#PG-STAT-ACTIVITY-VIEW> view's information about what a process is waiting for (Amit Kapila, Ildus Kurbangaliev) Historically a process has only been shown as waiting if it was waiting for a heavyweight lock. Now waits for lightweight locks and buffer pins are also shown in pg_stat_activity. Also, the type of lock being waited for is now visible. These changes replace the waiting column with wait_event_type and wait_event. How do I correct this?
