Create a GUC parameter temp_tablespaces that allows selection of the

Browse Source 
tablespace(s) in which to store temp tables and temporary files.  This is a
list to allow spreading the load across multiple tablespaces (a random list

not stored in per-database pgsql_tmp/ directories anymore, but per-tablespace
directories.
