Wrong performance data on custom_query

[majales]

I have found GraphiteWriter complaining about bad performance data from check_postgres.

warning/GraphiteWriter: Ignoring invalid perfdata value: subscription_name=db_partial_set;down

In fact check is returning bad performance data with "warning" value added to the perfomance data.

'/usr/lib/nagios/plugins/check_postgres.pl' '--action' 'custom_query' '--query' 'SELECT subscription_name, status AS result  FROM pglogical.show_subscription_status();' '--valtype' 'string' '-H' 'localhost' '-db' 'db' '-u' 'icinga' '-w' 'down'
POSTGRES_CUSTOM_QUERY OK: DB "db" (host:localhost) replicating | time=0.04s subscription_name=db_partial_set;down

I'm using latest check_postgres version.

/usr/lib/nagios/plugins/check_postgres.pl --version
check_postgres.pl version 2.25.0

Is there any workaround how to switch off perfdata? Thanx
