JDBC compliance - Mailing list pgsql-jdbc

Hello

I'm using the current release of PostgreSQL 7.2.1 on Mac OS X 10.1.5.
I'd like to know
how I can get the metadata from a tables columns ( getColumns( catalog,
scheme, table,column ) ).

I tried getColumns( null, null, tableName, null ); because there is no
scheme-concept
within postgresql. Also I tried getColumns( catalog, null, tableName,
null ), but nothing
helps.

What's the problem. Is the current driver able to get all the required
meta data from
the database???

Thanks for help
