Just to point out, there was a discussion I can't find right now about
fsync and create database optimization earlier this year.  Apparently
grouping everything together resulted in a big performance gain for
create database.  So it really is likely that a different version
could be much slower.  However, if you're both hitting the same db,
then the slowness is in the gui tool, not pgsql.
