Hash indices for some data types don't work, for example for time and date.

- submitted by: Massimo Dal Zotto <dz@cs.unitn.it>

The updating of array fields is broken in Postgres95-1.01, An array can
be only replaced with a new array but not have some elements modified.
This is caused by two bugs in the parser and in the array utilities.
Furthermore it is not possible to update array with a base type of
variable length.

I have written some patches which add support for NULLs to Postgres95.
In fact support for NULLs was already present in postgres, but it had been
disabled because not completely debugged, I believe. My patches simply add
some checks here and there. To enable the new code you must add -DNULL_PATCH
to CFLAGS in Makefile.global. After recompiling you can do things like:

insert into a (x, y) values (1, NULL);
update a set x = NULL where x = 0;

You can't still use a "where x=NULL" clause, you must use ISNULL instead.
This could probably be an easy fix to do.

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.

'select distinct on' causes backend to crash

submitted by: Chris Dunlop    chris@onthe.net.au

This is a patch to prevent an endless loop occuring in the Postgres backend
when a 'warning' error condition generates another warning error contition
in the handler code.

It is not possible to define attributes as arrays of date or time, the
type _time and _date are not defined.

Submitted by: Massimo Dal Zotto <dz@cs.unitn.it>

The type _char16 (array of char16) is incorrectly defined as array of name
and values longer than 16 chars are stored as names and not truncated to 16
bytes as they should be.

before (plus some optimisations/bug fixes et al).  I've included a small
demo transcript below. Note that all of of the display
functionality/intelligence you see here, can be had merely by calling
the new LIBPQ PQprint() routine with the appropriate arguments/options,
including the HTML3 output guff.
