[check_postgres] query_time alert is triggered by autovacuum jobs

[Aleksey Tsalolikhin]

Hi.  check_postgres.pl version 2.15.4.

I'm having trouble with the "query_time" check, it gets triggered by
autovacuum jobs.

I've tried adding --excludeuser=postgres (as autovacuum is run under
the db superuser account) but I'm still getting alerts on autovacuum
jobs.

Any suggestions for how to exclude autovacuum?  I do want to be
alerted on long-running queries, but not autovacuum processes.

Yours truly,
Aleksey
