Subject: explosive WAL growth
Date: Tue, 27 Feb 2024 11:09:58 -0700
Message-ID: <C7733827-4E85-47AF-8D39-349D007E229A@elevated-dev.com> (raw)

Something is causing our WAL to grow 160GB/hour *faster* than archiving. (Archiving appears to be working normally.) This started in the past couple of days.

I am having some trouble finding the cause of this. I am looking at pg_stat_statements, # calls, time, shared blocks written. I am also looking at recent client app deployments.

My next step might be to use something like pg_waldump to see what's in this WAL.

Any suggestions?
