Attached is a patch to address this.
After much consideration and deliberation, I went with the simpler
solution to simply dump out the database privileges based on what a new
creation of those privileges would yield, resulting in output similar to
pre-9.6. We document that template1 is allowed to be dropped/recreated,
which greatly complicates using pg_init_privs to record and produce a
delta against the initdb-time values, as we lose the connection between
pg_init_privs and the "template1" database as soon as it is dropped
(something which can't be done with objects in that catalog).
Comments welcome.
Thanks!
