F.31. pgAudit Log to File
F.31.2. Description
pgAudit Log to File is an
addon to pgAudit than will redirect audit log
lines to an independent file, instead of using the PostgreSQL server logger.
This will allow us to have an audit file that we can easily rotate without polluting server logs with those messages.
Audit logs in heavily used systems can grow very fast. This extension allows to automatically rotate the files based in a number of minutes.
F.31.3. Installation
Add
