Postgresql Tools
- Phppgadmin - I think you should reevaluate your outright dismissal of this tool. It has a larger feature set than PgAdmin III and allows you to connect over the local socket rather than strictly over the tcp port via JDBC.
- Aqua Data Studio - I used to use this tool quite often, but I'm unsure of its current status. It supports ER maps and has a number of features that are useful to developers.
I doubt you will find everything that you want in a single tool. I a lot of development using Postgresql and I still find myself the most efficent with a nice text editor and the command line psql tool.
