Thank you for the patch.
My high level review comment:
The patch seems to be implementing a useful and requested feature.
The patch applies cleanly and passes the basic regress tests. Also the commitfest bot is happy.
A first pass at the code, has not revealed any worthwhile comments.
Please allow me for a second and more thorough pass. The commitfest has hardly started after all.
Also allow me a series of genuine questions:
What would the behaviour be with REVOKE?
In a sequence similar to:
GRANT ALL ON ...
REVOKE pg_read_all_data FROM ...
What privileges would the user be left with? Would it be possible to end up in the same privilege only with a GRANT
command?
Does the above scenario even make sense?
Regards,
