pgadmin very slow

Hi<br /><br />We have very large databases with about 1000 tables (most of them partitions).  PGAdmin takes forever
(atleast3-5 minutes) just to open the browser for the database. This makes it almost un-usable.<br />I use Postgres
8.1.9 .   It works fast for small databases (having the same number of tables..)...as the database size keeps
increasing..thereis a progressive slowdown in PGAdmin. Our Databse is over 600Gb . <br /><br />is there any fix / patch
Ican use? It is a great toool but the slowness makes it unable to be used as a browser.<br />
