I'd name it ExecGrant_common() or such instead - ExecGrant_generic() sounds
like it will handle arbitrary things, which it doesn't. And, as you mention,
we could implement e.g. ExecGrant_Language() as using ExecGrant_common() +
additional checks.

Perhaps it'd be useful to add a callback to ExecGrant_generic() that can
perform additional checks, so that e.g. ExecGrant_Language() can easily be
implemented using ExecGrant_generic()?

Very neat.


It seems wrong that most (all?) ExecGrant_* functions have the
  foreach(cell, istmt->objects)
loop. But that's a lot easier to address once the code has been
deduplicated radically.
