"Block 503414" is a red flag here --- that means that this temp file
alone required 503414 * 8K = nearly 4Gb. I suspect /var/lib/pgsql has
been symlinked someplace else, as the root device has clearly not got
anything close to that much free space. It's quite possible that the
query involved multiple temp files, though, so maybe one of the other
partitions is getting filled.
