Postgres manually alter sequence

Question

I\'m trying to set a sequence to a specific value.

SELECT setval(\'payments_id_seq\'), 21, true

This gives an error:

Answer 1

The parentheses are misplaced:

SELECT setval('payments_id_seq', 21, true);  # next value will be 22

Otherwise you're calling setval with a single argument, while it requires two or three.
