Is there a way to get postgres to write a line to the log file when it
creates a WAL file? We wrote a script that tries to grab the times between
WAL file creation and ingestion without stopping to make absolutely sure
that postgres actually logs the WAL file creation, and so we're kinda stuck
staring at our screens and blinking.
Seriously. It took me a good five minutes to muster the brain power to
write this email.
