anoder important point of view forme:

As I know the size of sort_mem is given at the pg start
and is not shared.
Also I can use set sort_mem to xxx;
Can I dot set sort_mem to myvalue ; execute my query , set sort_mem to old_value; only
for querys that needet more sort memory?

If I can so will the new seted sort_mem be only for the opened connection or for connections?
Also will this dynamic sort_mem setting cause problems in pg?
