OK, cancel the question, the answer is
SELECT current_setting('global.val2');
This is very intriguing, but I'd like to make sure it is doing what I
think it is doing. Is it tracking variables in a connection across
SQL commands? If so, shouldn't this work (Assume the existence of
table "detail" with a column called "val2").
create or replace function SetVal2() returns void as
$$
begin
update detail set val2=global.val2;
end;
$$
language plpgsql
set global.val2=5;
select SetVal2();
I'm getting the following error which I don't understand. Seems I
don't know how to access the variable once it is set.
ERROR: missing FROM-clause entry for table "global"
CONTEXT: SQL statement "update detail set val2=global.val2"
PL/pgSQL function "setval2" line 2 at SQL statement
