Hi,
I have noticed that it is possible to create duplicate CHECK (haven't tried
other) constraints in 7.0.3 by doing something like this:
CREATE TABLE "test" ( "a" int4, CHECK (a < 400), CONSTRAINT "$1" CHECK (a > 5)
);
I was just fiddling around with trying to implement the 'DROP CONSTRAINT'
code (it's quite hard - don't wait up for me!) and it would seem to be a bad
thing that it's possible to have two constraints with the same name in a
table.
Surely there should be a UNIQUE (rcrelid, rcname) on pg_relcheck?, or at
least better checking in the CREATE TABLE code?
