DROP DATABASE and prepared xacts

I was just testing autovac once more, and happened to Ctrl-C the
regression run in the prepared_xacts test.  Upon starting Postmaster
again, I see this:

LOG:  recovering prepared transaction 14372
LOG:  recovering prepared transaction 14377


Then, I reran "make check", and got

============== dropping database "regression"         ==============
ERROR:  database "regression" is being accessed by other users
command failed: "/pgsql/install/00head/bin/psql" -X -c "DROP DATABASE IF EXISTS \"regression\"" "postgres"


I think we should set things up so that prepared transactions are
dropped when they concern a database being dropped.  Opinions?

Any takers? ;-)
