Re: gathering ownership and grant permissions

Thanks for the quick response.

That does not work for what I need because I only need the owner and
permissions of one table, I need the grant to look like the output that
pg_dump displays.

ex:

GRANT ALL ON TABLE testing_cdc TO bob;

--
-- PostgreSQL database dump complete
--

I need a way which my script can isolate the owner's name and set it to
a variable on its own. Same with grant.

Thanks
