Not so easily as all that. The .bki mechanism is pretty darn restricted
as to what it can generate, because of the limitations of bootstrap
mode. (And when you are starting up without pg_proc or pg_type, it's
not trivial to remove those restrictions either.)
I thought for a bit about1. Clone newdb from template0 (which we assume doesn't change)2. pg_dump template1 |
pg_restorenewdb
but pg_dump isn't terribly fast, and in any case this still has issues
--- eg, if DBA has dropped the public schema in template1, it will fail
to propagate that fact.
