Here's my fork of this that adds in functions as well: https://gist.github.com/bspkrs/b997ed7f1eb1268f3403
Thanks for the original!

Here's my fork that updates tables not in 'pg_catalog' schema https://gist.github.com/RockyMM/dd89aed75f3de9a2cd76 This is since the tables in my database are prevalently not in "public" schema.

Thanks a lot, great script!!

This uses ALTER TABLE on sequences and views... it should probably use ALTER SEQUENCE and ALTER VIEW, respectively.

Great script. Thank you.

Here is my updated version that includes a --dry-run mode, which will list what objects will be transferred (good for checking before and after). Also, I've added support for custom enum types:
