My application broke in a big way with the security update to 8.2.2 so
I hope this is a bug in 8.2.2 and not an intentional breakage of
backwards compatibility in a security update ;).

Actually I'm using the REL8_2_STABLE branch in CVS which may be a bit
more advanced than the plain 8.2.2, but still it's supposedly a stable
branch.

The easiest way for me to reproduce is this:

cpushare=> create table x (x NUMERIC(28,2) CHECK(x >= 0));
CREATE TABLE
cpushare=> insert into x values (0);
INSERT 0 1
cpushare=> update x set x = 0;
ERROR:  attribute 1 has wrong type
DETAIL:  Table has type numeric, but query expects numeric.
cpushare=>

Comments welcome. Thanks!
