Dear friends,

Thank you for your previous answers. I am running into a systemic
problem using Drupal under PostgreSQL 8.4

Drupal relies heavily on a domain derived from int:

CREATE DOMAIN int_unsigned
  AS integer
   CONSTRAINT int_unsigned_check CHECK ((VALUE >= 0));

Analysing slow queries, I noticed that PostgreSQL 8.4 would cast data
from int4 to int_unsigned.



Isn't that cast effectively a no-op?

cheers

andrew
