Comments:
1. It seems like the check for a "<<none>>" context should go into
sepgsql_object_relabel() directly rather than exec_object_restorecon().
The former gets registered as a hook in _PG_init(), so the with the
current location we would fail to skip the relabel when that gets
called.
The intent is not to stop all relabeling only to stop sepgsql_restorecon
from doing a bulk relabel. I believe sepgsql_object_relabel is called by
the 'SECURITY LABEL' statement which I'm using to set the label of db
objects to a specific context which I would not want altered later by a
restorecon.
Ok, sounds reasonable. Maybe just add a comment to that effect.
