pg_upgrade doesn't work if the 'postgres' database has been dropped in
the old cluster:
~/pgsql.master$ bin/pg_upgrade -b ~/pgsql.91stable/bin -B bin/ -d
~/pgsql.91stable/data -D data-upgraded/
Performing Consistency Checks
-----------------------------
Checking current, bin, and data directories ok
Checking cluster versions ok
Checking database user is a superuser ok
Checking for prepared transactions ok
Checking for reg* system OID user data types ok
Checking for contrib/isn with bigint-passing mismatch ok
Creating catalog dump ok
Checking for prepared transactions ok
New cluster database "postgres" does not exist in the old cluster
Failure, exiting
That's a bit unfortunate. We have some other tools that don't work
without the 'postgres' database, like 'reindexdb -all', but it would
still be nice if pg_upgrade did.
