d13fe29000 I have a problem with Access97 not working properly when entering new 
records using a sub form, i.e. entering a new order/orderlines or master
and
detail tables.  The problem is caused by a SQL statement that Access97
makes
involving NULL.  The syntax that fails is "column_name" = NULL.  The
following attachment was provided by -Jose'-.  It contains a very small
enhancement to gram.y that will allow Access97 to work properly with sub
forms.  Can this enhancement be added to release 6.5?

 <<gram.patch>>
Thanks, Michael

b4def32439 Include some new code for outer joins. Disabled by default, but enable by 
including the following in your Makefile.custom:

449020f782 Put in explicit checks for implicit index name lengths. 
Put in hooks for outer joins by passing a few parameters back and forth
 in function calls. May not be close to working yet.

03d5c070f0 Modify the outer join placeholder code with something closer to working 
code. Works here, but not completely implemented past this point.

Ok. I made patches replacing all of "#if FALSE" or "#if 0" to "#ifdef
NOT_USED" for current. I have tested these patches in that the
postgres binaries are identical.

Bruce Momjian
eb3415538e OK I found it, 
I search in the planner for the '\xFF' appending.
Finally I found in MakeIndexable() in gram.y

Attach a patch which removes the "<=" test in USE_LOCALE,
might make some queries a bit slower for us "locale-heads",
BUT correct result is more important.

        regards,

Included patches fix a portability problem of unsetenv() used in
6.4.2 multi-byte support. unsetenv() is only avaliable on FreeBSD and
Linux so I decided to replace with putenv().

c91dbcc5c7 The following patch finishes primary key support. Previously, when 
a field was labelled as a primary key, the system automatically
created a unique index on the field.  This patch extends it so
that the index has the indisprimary field set.  You can pull a list
of primary keys with the followiing select.

SELECT pg_class.relname, pg_attribute.attname
    FROM pg_class, pg_attribute, pg_index
    WHERE pg_class.oid = pg_attribute.attrelid AND
        pg_class.oid = pg_index.indrelid AND
        pg_index.indkey[0] = pg_attribute.attnum AND
        pg_index.indisunique = 't';

There is nothing in this patch that modifies the template database to
set the indisprimary attribute for system tables.  Should they be
changed or should we only be concerned with user tables?
