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.
