Sure we have --- up till recently, pg_temp files just lived in the
database directory. I think it was you that added the pg_temp
subdirectory, and the reason you did it was to let people symlink the
temp files to someplace else. But that's just a zeroth-order
approximation to providing a tablespace facility for these things.
