Allow CURRENT_ROLE where CURRENT_USER is accepted

Browse Source 
In the particular case of GRANTED BY, this is specified in the SQL
standard.  Since in PostgreSQL, CURRENT_ROLE is equivalent to
CURRENT_USER, and CURRENT_USER is already supported here, adding
CURRENT_ROLE is trivial.  The other cases are PostgreSQL extensions,
but for the same reason it also makes sense there.
