I'm not very experimented in Postgres but I think that you have to double-quote your table and column names only if you double-quoted them during creation time... Otherwise, they should have been created without any capslock and are case insensitive...

I have to " " my table and column names, and being new of course I didn't. Is there a way to remove this requirement? Thanks everyone for your help.
