pgsql: Create a GUC parameter temp_tablespaces that allows selection of - Mailing list pgsql-committers

Log Message:
-----------
Create a GUC parameter temp_tablespaces that allows selection of the
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
element is chosen each time a temp object is to be created).  Temp files are
not stored in per-database pgsql_tmp/ directories anymore, but per-tablespace
directories.
