Hi everyone,
I have a Postgres 9.3.3 database machine. Due to some intelligent work on the part of someone who shall remain
nameless,the WAL archive command included a ‘> /dev/null 2>&1’ which masked archive failures until the disk entirely
filledwith 400GB of pg_xlog entries.
I have fixed the archive command and can see WAL segments being shipped off of the server, however the xlog remains at
astable size and is not shrinking. In fact, it’s still growing at a (much slower) rate.
I’ve seen references to people just deleting “old” segment files or using pg_resetxlog to fix this situation, however I
alreadyknow that the response from the mailing list will be “that’s insane, don’t do that”.
So what is the correct solution to pursue here? The steady state of the machine should have enough space, I just need
toreclaim some of it... Thanks for any guidance!
Steven
