I'd like to wrap this one up, so I spent some time revising the patch
(attached).  Its just about ready to merge.  Is the neverallow really
needed?  Also, I'd still strongly urge you to reconsider adding the
postgresql_contexts file with the default object labels.  I think this
is the clearest example why:

type_transition postgresql_t postgresql_t:db_database sepgsql_db_t;

What object is being transitioned on?  Other type transitions are
clearer: a file being created in a directory or a message enqueued to a
message queue.  I won't block merging the policy over this, but I think
the postgresql_contexts is the better method.
