enable_seqscan shouldn't affect plain inserts, but it will affect
*every* query in the system.

I would suggest using setting  "prepareThreshold=0" in the JDBC driver
connection URL, or calling pstmt.setPrepareThreshold(0) in the
application. That tells the driver not to use server-side prepare, and
the query will be re-planned every time you execute it with the real
values of the parameters.
