Fix ALTER TABLE / INHERIT with generated columns

When running ALTER TABLE t2 INHERIT t1, we must check that columns in
t2 that correspond to a generated column in t1 are also generated and
have the same generation expression. Otherwise, this would allow
creating setups that a normal CREATE TABLE sequence would not allow.
