PG Settings Checksum feature does not work as expected

[keithf4]

Describe the issue:
The checksum generated by a psql connection that the user would use to set what should be the "valid" checksum will likely never match the checksum that is generated by the monitoring user when it connects from the exporter. Therefore it will always appear invalid. Even seeing the checksum change between different exporter sessions

Right now, not sure how this feature can work as expected. Will likely have to deprecate it for now until a different method to generate the hash that will match what the exporter expects can be found.

Tell us about your environment:

• pgMonitor version: All
• Container or non-container:
• Container name / image:
• Operating System for non-container:
• PostgreSQL Version:
• Exporter(s) in use (incl. version):
• Prometheus version:
• AlertManager version:
• Grafana version:

Someone else reporting similar issues upstream in sql_exporter just experimenting with settings in another manner.

Appears even choosing a different driver could cause the settings returned to be different than others
