Never got a reply on -bugs... do people think this is an issue?

----- Forwarded message from "Jim C. Nasby" <jnasby@pervasive.com> -----
decibel@phonebook.1[17:32]~:1%createdb test;
CREATE DATABASE
decibel@phonebook.1[17:32]~:2%dropdb test; createdb test;
DROP DATABASE
createdb: database creation failed: ERROR:  source database "template1"
is being accessed by other users
decibel@phonebook.1[17:32]~:3%

I realize that the changes made in 8.1 WRT using the postgres database
fix this particular case, but is there a bigger issue with there being a
race condition here? Presumably dropdb returns before the connection is
actually closed from the database's standpoint...
