Hi Alban,

If I do:
select * from SourceCategory

pgAdmin gives me an error: ERROR:  relation "sourcecategory" does not exist

If I do:
select * from "SourceCategory"

It works OK.

As Richard mentioned, it's because table was probably created with CREATE TABLE "SourceCategory".
I was not sure about this because I had no control over creating the tables.

What are you trying to fix that you don't just write SELECT
Column1,Column2 from MyTable ?
Postgres understands that fine, why do you want to quote those
identifiers? Maybe your application code is case-sensitive with
regards to column (and maybe table) names?
