I want to do that because, I have a partitioned table (big_table) and others (t1,t2,t3,t4) have foreign keys reference to big_table and i had many trobules at insert data, reading the doc:
"A serious limitation of the inheritance feature is that indexes (including unique constraints) and foreign key constraints only apply to single tables, not to their inheritance children. "

This seems really dangerous. You're certainly missing the pg_depend
linkages, not to mention attribute inheritance counts in pg_attribute,
and there may be other things I'm not remembering offhand.
Why can't you use the normal ALTER TABLE approach?
