Support Security Service Provider Interface (<acronym>SSPI</>) for Add a <varname>temp_tablespaces</varname> parameter to control

Albert Cervera, Bernd Helmle)
</para>

This parameter defines a list of tablespaces to be used. This
enables spreading the I/O load across multiple tablespaces. A random
tablespace is chosen each time a temporary object is created.
Temporary files are no longer stored in per-database

directories.

Support a global SSL configuration file (Victor Wagner) Place temporary tables' TOAST tables in special schemas named

This allows low-level code to recognize these tables as temporary,

fixes a bug wherein backends unexpectedly held open file references
