+ temp_tablespaces (string)
+
+ temp_tablespaces configuration parameter
+
+ tablespacetemp
+
+
+ This variable specifies tablespaces in which to create temp
+ objects (temp tables and indexes on temp tables) when a
+ CREATE command does not explicitly specify a tablespace
+ and temp files when necessary (eg. for sorting operations).
+
+
+
+ The value is either a list of names of tablespaces, or an empty
+ string to specify using the default tablespace of the current database.
+ If the value does not match the name of any existing tablespace,
+ PostgreSQL will automatically use the default
+ tablespace of the current database.
+
+
+
+ The first tablespace that will be used is choosen randomly from the
+ list, starting from that we cycle through the list in order.
+
+
+
+ For more information on tablespaces,
+ see .
