In the 8.4 branch, the error is coming from here:
regression=# \set VERBOSITY verbose
regression=# ALTER TABLE test ALTER COLUMN a TYPE numeric;
ERROR: 42P16: constraint must be added to child tables too
LOCATION: ATAddCheckConstraint, tablecmds.c:4467
which appears to have been added in commit cd902b331. I think the
commit Pavan is looking at just moved the logic around.
