Patrick,
Could you simply place some strtolower() or strtoupper() in the code?
Or are is it when you do something like `pg_fetch_array($resource);` that it
becomes an issue?

It does matter because when it comes back to PHP, the keys in the array are
lowercase, even though the query specified them as uppercase. In the past
(with MySQL) we've always been able to rely on the database returning keys
in the same case as we specify -- PHP arrays are case sensitive, which is
where the problem comes in.
If we have the query, 'select ID, USERNAME from USERS' with a MySQL
database, we'd get an associate array with 'ID' and 'USERNAME' being the
keys. The same query with Postgres will give us keys of 'id' and 'username',
which is different.
The goal of what we want to do is to be able to use the same code no matter
which database we are using. We ultimately will switch to a lowercase
convention to accommodate Postgres, but I'm trying to find out if that
really is the only option. The quoting technique does not work either
because MySQL handles it differently.
