Interesting. This is happening because we are connecting to one
database to create the new database, and then connecting to the new
database to add the comment.

Prior to PG 8.2, this was necessary to put the comment on the database,
but now that we have the shared comment/description table
pg_shdescription, this is not necessary.

Do we need createdb to be able to create databases for pre-8.2 clusters?
If not, the attached patch fixes the double-prompting.

Also, why is this code used to create the new database?

conn = connectDatabase(strcmp(dbname, "postgres") == 0 ? "template1" : "postgres",
host, port, username, prompt_password, progname);

Do we assume more users can connect to the 'postgres' database, but we
want 'postgres' to connect to 'template1' in case it wants to drop the
'postgres' database? Whatever the purpose, this code certainly needs a
comment.
