select max(id) from table;

will get you the max value, then you want to add one to that
number, and do this:

select setval('sequence_name', newvalue);

# I've exported a table from an existing MSAccess database to my
# PostgreSQL db.
# I use a serial ID on the table and now I'm getting errors when I add a
# new entry in the table if i don't specify the ID by hand (which should
# be placed automatically by the db since it's a serial).
#
# The exact error is this one:
#
# Cannot insert a duplicate key into a unique index.
#
#
# I think I should set the "last_value" field in the sequence to my real
# last value aon the ID field of the table, but Idon't know how to do it.
# Is there anybody who can help me ?
