Hi
I am playing with new features in Postgres 18.
Maybe I found a bug
(2025-03-18 19:28:06) postgres=# create table foo(a int constraint gzero check(a > 10) NOT ENFORCED);
CREATE TABLE
(2025-03-18 19:29:37) postgres=# insert into foo values(0);
INSERT 0 1
(2025-03-18 19:29:49) postgres=# insert into foo values(6);
INSERT 0 1
(2025-03-18 19:29:55) postgres=# alter table foo alter constraint gzero enforced;
ERROR: FOREIGN KEY constraints cannot be marked ENFORCED
LINE 1: alter table foo alter constraint gzero enforced;
I know so altering enforcing constraint is not supported yet, but the error message is surely wrong
gzero is not foreign key constraint

Pavel
