Add pg_identify_object_as_address

Browse Source 
This function returns object type and objname/objargs arrays, which can
be passed to pg_get_object_address.  This is especially useful because
the textual representation can be copied to a remote server in order to
obtain the corresponding OID-based address.  In essence, this function
is the inverse of recently added pg_get_object_address().

Catalog version bumped due to the addition of the new function.

Also add docs to pg_get_object_address.
