PRIMARY KEY implies NOT NULL. Are you sure the value being inserted
is NULL and not, for example, an empty string? What's the output of
the following query (use your own table and column names)?

SELECT pkcolumn, length(pkcolumn), pkcolumn IS NULL FROM tablename;

Are you sure the column has a PRIMARY KEY constraint? If you connect
with psql, what's the output of the following command?

\d tablename
