JDBC driver DatabaseMetaData.getTables() unconditionally lowercases tableName pattern

Dave Barnett (dave(at)lions(dot)med(dot)jhu(dot)edu) reports a bug with a severity of 2
The lower the number the more severe it is.

Short Description
JDBC driver DatabaseMetaData.getTables() unconditionally lowercases tableName pattern

Long Description
According to Chapter 2 of the User's Guide, NAMES may be quoted to preserve case. In the JDBC driver found in Postgres 7.0.2, jdbc2/DatabaseMetaData.java repeatedly converts the name pattern automatically to lowercase. Removing these improper conversions provides usable behavior.

I think the driver shouldn't be doing anything to the pattern, so that the user may handle case conversions as needed. Alternatively, the driver should simply not be doing this in the case that it is quoted.

Current workarounds:
1. modify driver code and recompile driver
2. provide a '%' tableName pattern and sift through all the tables in user code checking for proper matches
