Statement too long

Hello,

I have some problem with too long statement.
In 'psql', the error returned for my insert statement is
ERROR: Tuple is too big: size 10436

In fact, I use JDBC driver to insert a long long string into a 'text'
field. The exception is

The SQL Statement is too long - INSERT INTO TRIGGERQUEUE (DUETIME,
TYPE, EVENT, ACTION) VALUES( 974992122555, 'CONTAINER',
.....(long really long).......

So is it possible to re-build postmaster to avoid this limitation for
too long statement or is there another way in JDBC ?

Another problem is that with jdbc 6.5 and 7.0 the example of using largeobject
in postgreSQL development corner site does not work. It returns an exception:
setBinaryStream does not support an input as an InputStream.
So how to make this exemple work ?

Regards
