The \d command is a psql client feature. I has nothing to do with JDBC and
is not built into the server back-end (a few moments reading the source
code for psql would have shown you this). To obtain metadata through JDBC,
use the standard provided classes. If you don't know how to that then you
really need to learn JDBC. There's a good introductory tutorial on
java.sun.com
