I'm using gjournal for 5 weeks now on my production server.
There are 4 journaled filesystems on a raid controller with
BBU. pg uses 23GB out of 1.6TB. I can't see any performance impact or  
other issue.
Recovery from an unclean shutdown took less than a minute as compared  
to half an hour with ufs2/softupdates/fsck.
However I'm still unsure if I should enable async mounts of rhe fs  
with tablespaces/WAL.
Anybody giving me advice?
