Hi guys,

I've issue with Hibernate(4.2) mapping a PostgreSQL(9) database.

I have a join table which stores data as regclass type. This data is a String in the model object.

Select and Insert queries are working well, but testing queries when instantiating a collection returns an error regarding the equal test :

ERROR: operator does not exist: regclass = character varying
Hint : No operator matches the given name and argument type(s). You might need to add explicit type casts.
Position : 795

Is there any way to identify this attribute as a Regclass or to force the cast when a test is done ?

Thanks in advance,

LDF.
