I recommend you re-post to the pgsql-performance list, after reading
The one thing I can say based on the information you've provided so
far is that you can expect major performance improvements if you
upgrade to a new major release of PostgreSQL.
Well, there is one other thing -- it's almost never a good idea to
run VACUUM FULL. You may have bloated your indexes. You could try
a REINDEX on the database.
