List pgsql-general
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...

Hmm

Would seem I'm a bit of a dummy...  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.

Zac
