So I've got this patch (attached, against 8.2)
The goal is to track temp file usage as an aid to server tuning (such as
work_mem)
Most of the patch seems to work just dandy, except I'm getting weird
sizes reported:
2006-12-29 17:46:21 EST [45558]: [575-1] LOG: temp file: size 140737488343776 path base/32861/pgsql_tmp/pgsql_tmp45558.554
Seems a bit odd to have a 140T file on a 130G partition ...
I'm working on a FreeBSD 6.2 amd64 system. The headers show stat.st_size to
be of type off_t, which appears to be a 64-bit int. I figured that %ld
would be the correct format.
Am I hitting something such as file sparseness? Is this entire endeavour
doomed from the start? Or am I just making some sort of dumb mistake?
Any pointers are welcome.
