Hi all.
 
I'm planning to vacuum FULL a pg_largeobject relation (after vacuumlo'ing it). The relation is 300GB large so I'm concerned the operation will write full my pg_xlog directory which is on a 200GB (net) RAID1 SSD.
 
Where does vacuum FULL rewrite to, does it use pg_xlog or some other directory?
 
Thanks.
