Actually, the name of the table isn't correct.
You'll have created it using pgAdmin as an upper-case table, and are
trying to access it folded to lower-case (as in the error message).
If you create/query tables without quotes they get folded to lower-case.
Quoting creation/queries preserves case.
So:
CREATE TABLE "Foo" ...
SELECT * FROM "Foo" (works)
SELECT * FROM Foo (fails, gets folded to lower-case)
CREATE TABLE Bar ...
SELECT * FROM Bar (works)
SELECT * FROM BAR (works)
SELECT * FROM "bar" (works)
SELECT * FROM "Bar" (fails - it was created as lower-case)
You might find section 4.1 of the manuals useful, as well as the FAQ
http://www.postgresql.org/files/documentation/faqs/FAQ.html
In fact, if possible make a nice hot cup of tea/coffee, put a favourite
CD on, put up your feet and read the FAQ and first third of the manuals
before going any further. Time well spent, I can guarantee it.
