Using an Integrator as described exactly in this post to pull the Metadata from a PostgreSQL database. Most of the requested data is returned, such a column name.

With hibernate.hbm2ddl.auto=validate set in the properties file, the metadata types (ex. column.getSqlType()) are all null.

With* hibernate.hbm2ddl.auto=create* set in the properties file, the metadata types (ex. column.getSqlType()) are returned as expected.
