for against a just updated CVS tree. It contains
Partial new rewrite system that handles subselects, view
aggregate columns, insert into select from view, updates
with set col = view-value and select rules restriction to
view definition.
Updates for rule/view backparsing utility functions to
handle subselects correct.
New system views pg_tables and pg_indexes (where you can
see the complete index definition in the latter one).
Enabling array references on query parameters.
Bugfix for functional index.
Little changes to system views pg_rules and pg_views.
The rule system isn't a release-stopper any longer.
But another stopper is that I don't know if the latest
changes to PL/pgSQL (not already in CVS) made it compile on
AIX. Still wait for some response from Dave.

no longer returns buffer pointer, can be gotten from scan;
descriptor; bootstrap can create multi-key indexes;
pg_procname index now is multi-key index; oidint2, oidint4, oidname
are gone (must be removed from regression tests); use System Cache
rather than sequential scan in many places; heap_modifytuple no
longer takes buffer parameter; remove unused buffer parameter in
a few other functions; oid8 is not index-able; remove some use of
single-character variable names; cleanup Buffer variables usage
and scan descriptor looping; cleaned up allocation and freeing of
tuples; 18k lines of diff;
As an example I sent a bug-report on 26 Nov to tell that the fix included
below is necessary to compile pg95-current on Ultrix with Digital's
standard C compiler c89. In fact I think that this fix is needed
for any C compiler sticking very close the standard, see my discussion
in the original bug report.

Changes:
* Unique index capability works using the syntax 'create unique
index'.
* Duplicate OID's in the system tables are removed. I put
little scripts called 'duplicate_oids' and 'find_oid' in
include/catalog that help to find and remove duplicate OID's.
I also moved 'unused_oids' from backend/catalog to
include/catalog, since it has to be in the same directory
as the include files in order to work.
* The backend tries converting the name of a function or aggregate
to all lowercase if the original name given doesn't work (mostly
for compatibility with ODBC).
* You can 'SELECT NULL' to your heart's content.
* I put my _bt_updateitem fix in instead, which uses
_bt_insertonpg so that even if the new key is so big that
the page has to be split, everything still works.
* All literal references to system catalog OID's have been
replaced with references to define'd constants from the catalog
header files.
* I added a couple of node copy functions. I think this was a
preliminary attempt to get rules to work.
