Yes it does look like it's the insert that's at fault. I've tested it on a
current backend here and it has the same problem.

Peter,

Joseph Shraibman contacted me yesterday about whether or not the patch that
I
sent actually does the correct thing. I enclose my response below.

In brief, there seems to be some problem at the backend inserting a \0. I
have
tested the query from the modified jdbc driver, psql and a standalone
backend.

Regards,
Grant

I tested by doing the following:-
In psql...
CREATE TABLE t ( aa char(1) );
INSERT INTO t VALUES ('\0');

In java test program...     PreparedStatement ps =        conn.prepareStatement("insert into t values (?)");
ps.setString(1,String.valueOf('\0'));     ps.executeUpdate();
 

In psql...
test=# select * from t;aa
----


(2 rows)
test=# select ascii(aa) from t;ascii
-------   32   32
(2 rows)

This is wierd! Both psql and the java app insert the same value and both are
not 0.

However,
test=# select ascii('\0');ascii
-------    0
(1 row)

This appears correct, so the problem would appear to be in the insert.
