You'll need to run something like the below to set the next value to the
max current value. You'll just have to figure out the name of the sequence
that is automatically created whether you use the pseudo type serial, or
the newer IDENTITY option. Both are implemented with a sequence.

--set sequence to max ID on a table
select setval( 'table_name_id_seq', ( select max(id) + 1 from table_name )
);
