Marc G. Fournier f2f53aee0f Fixes: 
The comparison routines for text and char data type give incorrect results
if the input data contains characters greater than 127.  As these routines
perform the comparison using signed char variables all character codes
greater than 127 are interpreted as less than 0.  These codes are used to
encode the iso8859 char sets.
The other text-like data types seem to work as expected as they use unsigned
chars in comparisons.

Marc G. Fournier a7cfd65532 Fixes: 
Select queries with an isnull or notnull clause, like "select * where
somefield isnull", crash the backend if the table has at least one index.
If the indices are deleted the queries work again. Also the explain
command fail in the same way.
The is caused by a bug in subroutine of the optimizer which doesn't check
null values in the clauses.
