Question

I have a 500,000 line SQL script:

UPDATE users SET region_id = 9814746 WHERE id = 101 AND region_id IS null;
UPDATE users SET region_id = 9814731 WHERE id = 102 AND region_id IS null;
UPDATE users SET region_id = 3470676 WHERE id = 103 AND region_id IS null;

I want to INSERT a delay of 10 seconds every 50 lines. Does pgsql have a waitfor statement like t-sql.

Thanks.

Does pgsql have a waitfor statement like t-sql.

Yes, pg_sleep:

pg=> SELECT pg_sleep(10);
 pg_sleep
