New Postgresql import plugin

[Bruno Duyé <bduye easter-eggs com>]

Hi all,

I just wrote a Python Dia plugin to import Postgresql DB tables schemas 
into Dia.

I'm aware of Chris Daley's postgres.py plugin, but it didn't worked for 
me. The postgres requests where not working with my Postgres version. 
Since I'm not a Postgres expert, I don't really know when 
information_schema changed, but it seems to have changed a lot since 
Chris version.
I also needed to selectively include or exclude tables from schemas. 
Those two big differences made me fork Chris work. Hope he don't mind !

Here's the repo:

Cheers
