Thanks, it runs better (average 240s, not 700s) with the index. Rewriting
queries
as JOINs does not make any difference.
The last_snapshot is a temp table created earlier in the procedure
and the query in question is preceded with CREATE TEMPORARY TABLE as well,
not a cursor.
I still do not get why it performs differently inside the procedure.
Is there any way to see what planning decisions were made?
Best regards,
Michal
