Subject: | Statement setNull for Types.CLOB |

Hello, I'm using PostgreSQL 8 and the 310 build of the 8.0 JDBC3 driver
with Hibernate. For 'text' columns in my database, I had mapped them to
the Hibernate "text" type. When attempting to set the value of a text
column to 'null' via a PreparedStatement Hibernate calls setNull() passing
the Types.CLOB as the SQL type. The Postgres driver is throwing an
exception, however, saying that type is unknown.
I can easily change the Hibernate mapping to "string", which would change
the SQL type passed to setNull() to Types.VARCHAR, but I was wondering if
Types.CLOB should be a supported value in the setNull() JDBC method?
I realize it might not be correct to think of the PostgreSQL text type as
a CLOB, so I just wanted some insight on this issue if possible.
Thanks,

This problem was just reported for bytea/BLOB here:
http://archives.postgresql.org/pgsql-jdbc/2005-02/msg00115.php
The same situation applies, I've fixed the setNull call to do something,
but again CLOB really maps to the oid datatype in pg, not text.
