<li>A database can now be opened even if class of a user defined function is not in the classpath.
Trying to call the function will throws an exception.
</li><li>User defined functions and constants may not overload built-in functions and constants.
This didn't work before, but now trying to create such an object didn't fail.
</li><li>Improved MultiDimension tool (for spatial queries): in the last few releases the tool was actually
slower than using a regular query (because index lookup got faster, and because the tool didn't
support prepared statements) Now the tool generates prepared statements,
and the performance is better again (about 5 times faster for a reasonable amount of data).
</li><li>Adding a foreign key or when re-enabling referential integrity for a table failed when checking
was enabled and the reference contained NULL.
</li><li>For PgServer, character encoding other than UTF-8 did not work correctly. Fixed.
</li><li>Using a function in a GROUP BY expression that is used in a view as a condition did not always work.
