Re: updatable (J2EE) resultsets

The following adds support for updateable ResultSets with a mixed case
table name and column names.

What could really use some work is the parseQuery method in
org.postgresql.jdbc2.AbstractJdbc2ResultSet.  When determining if a
ResultSet can be updated it does not check that all colums of the result
set aren't derived columns.  The check to make sure it is a single table
is not particularly good.  It fails on things like:

SELECT CURRENT_TIMESTAMP;
SELECT a AS from FROM t;
SELECT a FROM t1 LEFT JOIN t2 ON (t1.id=t2.id);
SELECT a FROM t1 UNION SELECT a FROM t2;

I'm not sure how much this can be improved without building a full blown
parser into the driver.
