Have a look at Power*Architect: http://www.sqlpower.ca/page/architect
It's not perfect but it's quite OK.
As it is a multi-DBMS tool it does not support any Postgres specific features or datatypes.
To avoid the nasty registration that is required on their homepage you can also download the binaries directly from the Google code project homepage:
