Re: Bogus temp file reporting? - Mailing list pgsql-general

Hello,

Is there a known issue with temp file reporting?  I have a production db that is reporting 231TB of temp space usage, which can’t be true.  temp_blks_written in pg_stat_statements sort of confirms this, as the reported queries show just a few MB of temp space usage.  I suspect a reboot will clear this (to do) and wanted to check with you to see if someone else has had similar experiences.

Regards,

Kiriakos Georgiou
