Could you provide a complete test case?  That is, all SQL statements
that somebody could execute in an empty database to reproduce the
problem.  It doesn't have to be 100% reproducible as long as it
does exhibit the behavior every once in a while (an indication of
how often or under what circumstances, if known, would be helpful).

Is it possible that another session is altering the sequence to
start with a lower value?  Have you perchance set the sequence's
CACHE setting to a value other than 1 (one)?  What's the output of
"SELECT * FROM sequence_name"?  Are you making queries from more
than one session?  Are you using connection pooling?
