I found a bug in the jdbc driver

I have just found a bug in the latest jdbc driver.

The error is in the class org.postgresql.jdbc2.AbstractJdbc2ResultSet

the method parseQuery() has a bug:

if you give as sql query something like "SELECT * FROM tablename;", that is a
valid sql statement, and you try to use a resultset update method (like
updateInt()), you receive an SQLException saying: No Primary Keys. this is
because the method parseQuery() make a too simplified use of the
StringTokenizer, so the variable tableName is set at something like this:
"tablename;". So when the isUpdateable() method request for the primary keys of
the table 'tablename;', postgres answers there are no rows (it can't fond any
primary key for the table because it doesn't exists). The problem can be
resolved writing the sql statement very carefully: you must insert blanks
between any part of the sql statement (operators, keywords, ecc.). In my example
the solution is to insert a blank before the semicolon ("SELECT * FROM tablename
;").

I think i can resolve the problem, modifying the driver, but i wuold be glad to
know if someone else is already working at it now.

I hope this can be useful.

Inny.
