Re: explosive WAL growth - Mailing list pgsql-admin
Has any autovacuum, vacuum, or reindex occurred?
These operations generate lots of WAL depending on the size of the data related.

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?
