Hi
Iam trying to update a database table with approx 45000 rows. Iam not
updating all rows at a time. Iam updating 60 rows at a given time for
example. and this is happening in a FOR LOOP. A function that has the
update statements is called within the loop.
The updates take too long.....is postgres slow in doing updates on
large tables or is it because of the function call within the loop???
45000 rows isn't a large table, and there's no reason why it should be
slow in updating 60 rows.
Did you VACUUM ANALYZE; your table recently? Are the columns you use in
your WHERE indexed?
What does EXPLAIN ANALYZE say?
