I was trying to get a very nice FREE graphical db tool called DbVisualizer

(http://www.ideit.com/products/dbvis/) to work with Postgresql and I found
out the following bug: if database has views then getTables() gets the null
pointer exception ('order by relname' makes the listing tree in
DbVisualizer a lot useful !!)

This patch should propably be applied to the the jdbc1's
DatabaseMetaData.java, too.
