-commit 8d02e4c6c5e1e8676251b0717a46054267091cb4
-Author: Tristan Partin <tristan.partin@databricks.com>
-Date:   2025-06-23 02:09:31 +0000

-    Disable logging in parallel workers
-    
-    When a query uses parallel workers, pgaudit will log the same query for
-    every parallel worker. This is undesireable since it can result in log
-    amplification for queries that use parallel workers.

-    //    some reason, and you would be less likely to accidentally litter other parts of
-    //    the filesystem with e.g. temporary files. However, that's a pretty invasive
-    //    change.
-    //
-    // 2. On Linux, you could open() the data directory, and refer to the the socket
-    //    inside it as "/proc/self/fd/<fd>/neon-communicator.socket". But that's
-    //    Linux-only.
-    //
-    // 3. Create a symbolic link to the socket with a shorter path, and use that.
-    //
