You need to find out the SQL statement that triggers the error.
The error you quoted does not come from the JDBC driver, but from the database
I suggest that you set
log_min_messages to ERROR or lower,
log_min_error_statement to ERROR or lower, and
log_statement to all.
Then reproduce the error and look into the log file to find out the
statement that got the error. We can proceed from there.
