The -extend.query-path command-line argument specifies a YAML file containing additional queries to run.
Some examples are provided in [queries.yaml](queries.yaml).
### Working with non-officially-supported postgres versions
If you want to use this exporter to monitor a postgres installation that is not officially supported (e.g. 8.2.15) or a variant of postgres (e.g. Greenplum).
You may try to disable all internal metrics using the -disable-default-metrics command-line argument, then supply your own set of metrics definitions in
an external config file.
### Running as non-superuser
To be able to collect metrics from pg_stat_activity and pg_stat_replication as non-superuser you have to create views as a superuser, and assign permissions separately to those. In PostgreSQL, views run with the permissions of the user that created them so they can act as security barriers.
