That's normal. 32 meg isn't really that big. How big of a partition do
you have this database on? Your best bet is to put it on a bigger
partition. the pg_xlog directory is gonna be at least 16 megs for most
installations.
Do you have any transactions sitting at idle keeping postgresql from
recycling the xlogs?
Normally when you run out of space it's a lack of vacuuming, but here it
just sounds like either the partition is too small or the postgres user is
living under a quota on that partition.
