Hi everyone,
the statements below result in an error "ERROR: attribute 1 of type
t0 has wrong type":
CREATE TABLE t0(c0 VARCHAR(10));
INSERT INTO t0(c0) VALUES('');
ALTER TABLE t0 ALTER c0 SET DATA TYPE TEXT, ADD EXCLUDE (('a' LIKE
t0.c0) WITH =); -- unexpected: ERROR: attribute 1 of type t0 has
wrong type
This is unexpected, since breaking up the ALTER TABLE actions does not
result in this error:
CREATE TABLE t0(c0 VARCHAR(10));
INSERT INTO t0(c0) VALUES('');
ALTER TABLE t0 ALTER c0 SET DATA TYPE TEXT;
ALTER TABLE t0 ADD EXCLUDE (('a' LIKE t0.c0) WITH =); -- no error
Best,
Manuel
