Pavel,
There is no
DECLARE TEMP CURSOR
or
DECLARE TEMP variable in PLpgSQL
and
CREATE TEMP TABLE has a different meaning from what I understand you
envision for variables.
But maybe I'm mistaken. Your original post did not describe the entire
syntax:
CREATE [TEMP] VARIABLE [IF NOT EXISTS] name AS type
[ DEFAULT expression ] [[NOT] NULL]
[ ON TRANSACTION END { RESET | DROP } ]
[ { VOLATILE | STABLE } ];
Especially the TEMP is not spelled out and how its presence affects or
doesn't ON TRANSACTION END.
So may be if you elaborate I understand where you are coming from.
