Have you tried PGAdmin? You can use this graphical tool from windows.
It's very good and it's also free!

Hi.
I have a big problem with postgres because I need to know how I can see

relations among the table
I have a database and a table with 7 records (which i dont think it's

I join this table with another of about the same size and put a record
restriction (WHERE) and everything works out fine, but when I put two SUMs
over a couple of fields and add a GROUP BY I keep getting this
