Finding out whether a temporary file is in use any more

Because temporary files are not as carefully preserved as ordinary tables (this is actually one of the benefits of temporary tables, as less bookkeeping makes them faster), it may sometimes happen that a system crash leaves a few temporary files, which can (in the worst cases) take up a significant amount of disk space.

As a rule, you can clean up such files by shutting down the PostgreSQL server and then deleting all files from the pgsql_tmp directory.
