Pb with Spring & Metadat

Hello,

I want to get database information using metadata with Spring (1.2.4).
It's OK with postGre8.0, but when I use postGre8.1, error...

what about this function "information_schema._pg_keypositions()" ?

Caused by: org.springframework.jdbc.support.MetaDataAccessException:
Error while extracting DatabaseMetaData; nested exception is
org.postgresql.util.PSQLException: ERROR: function
