Yes, it can be done at least with GNU chmod by using chmod -R.
The problem is that it doesn't work too well for schemas -> tables,
because the set of acceptable privileges is completely different. So
the only case that would work is GRANT ALL. Perhaps what could work is
to be able to specify wildcards in GRANT, for example
GRANT SELECT, INSERT ON TABLE schema.* TO <role>
The problem with this idea is what happens if you create a new table in
that schema? Is the role given access to that table? (The other
problem is whether this new command conforms to the SQL standard, or is
it in conflict with it.)
