Not exactly suitable for pgBadger, but one could setup “csvlog” format, load logs into the dedicated table and analyse with SQL statements: http://www.postgresql.org/docs/current/interactive/runtime-config-logging.html#RUNTIME-CONFIG-LOGGING-CSVLOG I'm using this approach for quite some time. -- Victor Y.
