Alter table add constraint check #4120

griffio · 2023-04-28T18:07:37Z

Support for basic MySql and Postgres alter table constraint check.

Reuse of the inherited check_constraint in base sql-psi as current grammer expr doesn't work.

Add test fixtures for dialects

ALTER TABLE t1 
 ADD CONSTRAINT chk_c1 
 CHECK (c1 > 0);

Note: SQLite only supports a limited subset of ALTER TABLE, this excludes adding constraints.
