The following bug has been logged online:

Bug reference: 2501
Logged by: ALL
Email address: thegreatall@gmail.com
PostgreSQL version: 8.1
Operating system: Windows
Description: JOIN and capitial letters in Table Row
Details:

I had a table as like the following named products:

id ClientID ProductID is_multiqty is_active
1 12345 1000001 1 1
2 12345 1000002 0 1

and another table named productoptions with the following:

id ProductID Sku Description OptionID minpayments maxpayments maxqty is_acti
ve
1 1000001 somedesc1 1 1 1 0 1
1 1000002 CX7535 somedesc2 1 1 3 0 1

when I ran the following sql I got: ""ERROR: column product.ProductID does
not exist":

SELECT *
FROM products
JOIN productoptions
ON products.ProductID = productoptions.ProductID

However, if i changed the name of the fields in the database to:

"productid"

It would work fine.

TIP 2: Don't 'kill -9' the postmaster

If you define an object using quotes to preserve case, you must always
refer to that object with quotes, ie: productoptions."ProductID".

My recommendation: use underscores in the database
(product_options.product_id). Personally, I wouldn't pluralize the
table names either, but that's just me...

TIP 9: In versions below 8.0, the planner will ignore your desire to
choose an index scan if your joining column's datatypes do not
match
