Checkmk Werk 7423: mk_postgres: fix syntax error

ID: 7423 Title: mk_postgres: fix syntax error Component: Checks & agents Level: 1 Class: Bug fix Version: 1.7.0i1 Version 1.5.0p17 and 1.5.0p18 of the mk_postgres plugin gave a syntax error when parsing databases. This results in empty output between [databases_start] and [databases_end] in the plugin output. As a consequence the checks postgres_stats, postgres_bloat, postgres_connections, postgres_locks and postgres_query_duration become stale. To resolve the error the fixed version of mk_postgres has to be deployed to the affected hosts.
