The following documentation comment has been logged on the website: Page: https://www.postgresql.org/docs/16/sql-alterdomain.html Description:
(apologies, I managed to send this too soon, just now, somehow) The example for ALTER DOMAIN shows: ALTER DOMAIN zipcode ADD CONSTRAINT zipchk CHECK (char_length(VALUE) = 5); ...yet the syntax suggests no CONSTRAINT-keyword (I'm guessing?) should be used: ALTER DOMAIN name ADD domain_constraint [ NOT VALID ] When it should, I think?
