This has been considered and rejected before, on the grounds that
removing files you don't know the source of is a good way to lose data.
Come to think of it, that argument bears on the immediate problem too.
The way createdb() is coded, if it gets a failure (like "File exists")
trying to create the database's directories, it will attempt to apply
remove_dbtablespaces() to clean up after itself. This would result in
removing the pre-existing directory, which violates the principle of
not removing unexpected files. So now I'm starting to think we do need
a check-for-conflicting-files step in createdb.
