Обсуждение: next question, signed/unsigned

-----BEGIN PGP SIGNED MESSAGE-----

I'm trying to do what I can to help the phpwebsite guys get their app working
with postgres.  They're quite willing so I'm trying to do what legwork I can
for them.

Their script runs this during install:

CREATE TABLE cache ( mod_title varchar(30) NOT NULL default '', id varchar(32)
NOT NULL default '', data text NOT NULL, ttl int unsigned NOT NULL default
'0');

postgres doesn't like unsigned at all.  I can't really find a reference to
unsigned integers related to creating columns in the docs, so does this even
apply?  Should I just tell them to ignore it in postgres?

Postgres does not support the "unsigned" keyword.

Should they need, for some reason, the functionality of an unsigned integer,
you can always create a DOMAIN of int that does not permit values < 0.

But in either case, you'll need to modify the CREATE TABLE statements.
