ResultSet.getClob() causing problems when used with JPA's @Lob

Hi.

I have a varchar-column in a table which maps to a field (of type String) in a
JPA-entity. When marking that String-property with the JPA @Lob-annotation,
using Hibernate as my JPA-provider, it stops working as expected when using
PostgreSQL (works as expected on Oracle and SQL Server). The problem is that
Hibernate, correctly, calls ResultSet.getClob() but PG internally calls
getLong(), which obviously won't work with varchar-types, resulting in:

Caused by: org.postgresql.util.PSQLException: Bad value for type long : Hei

org.hibernate.type.descriptor.sql.ClobTypeDescriptor$4.doExtract(ClobTypeDescriptor.java:104)

After googling around I see this issue has come up before:
http://archives.postgresql.org/pgsql-jdbc/2010-02/msg00004.php

One is encurraged to use ResultSet.getString() instead. Hm, well - being at
Hibernate's mercy here, I don't really have that luxury. So, is PG's JDBC-
driver going to fix this flaw (IMNSHO it is a flaw) or is there consensus in the
PG-community that clobs are special and are not to be treated as
Strings/varchars?
