Ah, thanks, I had seen that but didn't quite associate it to this
comment.
Perhaps not a surprise, but I tend to favor predefined roles for these
kinds of things. If we do want to revamp how GRANT works, I'd argue for
first splitting up the way we handle privileges to be on a
per-object-type basis and once we did that then we could extend that to
allow GRANT on commands more easily (and with more variety as to what
privileges a GRANT on a command could be). It's kind of cute to have
one bitmap covering all objects but it puts us into a place where
extending what can be GRANT'd on one kind of object necessarily impacts
our ability to GRANT on other kinds (eg: we have a bit reserved for
TRUNCATE in the same bitmask for a schema as we do for a table, but we
don't allow TRUNCATE on schemas and probably never will).
Thanks,
Stephen
