This seems to be a bit over the top;
SELECT setval('seq', (SELECT MAX(seq_ID) FROM table)
should be enough. Even the +1 isn't necessary, as the first value the
sequence will return is already 1 higher than the value retrieved from MAX.
Are you sure you're using the correct sequence(s) to retrieve your
column values for the problematic table(s)? How do you set the values
for seqID?
Also note that a SERIAL type column is simply a macro for creating an
INT4 type column with a DEFAULT nextval('...'). You can easily change
your schema to include the defaults.
