The sequence functions are documented here:
https://www.postgresql.org/docs/current/functions-sequence.html
setval is the function you want. You can use a SELECT so you don't have to copy values around:
select setval('t_pk_seq', (select max(pk) from t));
That form of setval() sets the sequence so that the next value will be one more than the value you set it to, so you don't have to do max()+1 there.
