X-Git-Url: http://git.postgresql.org/gitweb/?a=commitdiff_plain;h=dbf42b84ac7b4e1dfd1ac6e618e247100b6aa08b;p=postgresql.git

Add tab-complete for ALTER DOMAIN ADD  [CONSTRAINT]

We can add tab-completion with "CHECK (" and "NOT NULL" after ALTER
DOMAIN ADD [CONSTRAINT].

ALTER DOMAIN dom ADD -> CHECK (
ALTER DOMAIN dom ADD -> NOT NULL
ALTER DOMAIN dom ADD -> CONSTRAINT
ALTER DOMAIN dom ADD CONSTRAINT nm -> CHECK (
ALTER DOMAIN dom ADD CONSTRAINT nm -> NOT NULL
