Hello all,
I'm running 7.1RC2 and have a question/problem:
I have a table which is 28150 pages in size. It has two indices
of 8001 and 9750 pages.
The filesystem on which pg_xlog resides has ~750MB free.
No other PostgreSQL work is running.
Yet, when running VACUUM ANALYZE on this table, I run out of
space.
Here's the snippet where it breaks:
DEBUG: XLogWrite: new log file created - consider increasing WAL_FILES
DEBUG: XLogWrite: new log file created - consider increasing WAL_FILES
DEBUG: Rel booking: Pages: 28150 --> 22814; Tuple(s) moved: 146717. CPU 168.87s/229.66u sec.

/opt/postgresql/bin/postmaster: Startup proc 29468 exited with status 512 - abort
It appears the VACUUM ANALYZE requires >3x the table size in
order to run?
I don't recall seeing this behaviour on my other box, but that
my just be because it has an obscene amount of free space on the
$PGDATA filesystem.
Thanks,
Gordon.
