Re: [GENERAL] After upgrade to 9.6: waiting column does not exist

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 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?

are you running some sort of monitoring software thats periodically looking at pg_stat_activity ?   whatever query its doing needs to be rewritten to take into account the pg_stat_activity changes in 9.6
