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?
