Problem to solve
Support ability to audit a postgres cluster
Further details
For enterprise SOX compliant deployments, there's a need to have configurable auditing option. Currently, Stackgres doesn't provide this out of the box.
Proposal
Please add pgAudit to the list of available extensions. Also allow for filtering and searching through log audit entries.
Acceptance Criteria
PgAudit can be installed from the list of available extensions.
