Hello,
i've found a strange behaviour when you have overloaded functions with
the same name and different argument types and try to call them with NULL.
The stored procedures with "text" and "text[]" argument type gets called
- the variants with "integer" / "integer[]" produce the, i think
expected, behaviour and raise an exception "ERROR: FUNCTION
foo(unknown) IS NOT UNIQUE".
Is there an explanation or is this a bug?
I've tested this on PG 8.3.1 and 8.2.4, see

Best regards,
Patryk Kordylewski
