attached to this mail is a patch from a colleague that makes
PostgreSQL-7.0.2 run on Linux for the Intel-IA64 architecture. It also
fixes a bug in the configure scripts that caused configure to fail on
the fcntl(F_SETLK) test.
This fix triggered a bug in the fcntl(F_SETLK) code of the Linux
kernel when used on unix domain sockets resulting in postmaster to
segfault immediately after startup. There is a fix available and
included in the kernel that will be on SuSE Linux 7.0, but kernels <=
2.2.16 still have this bug.
Expand secondary password file feature, so that you can use these
files to restrict the set of users that can connect to a database
but can still use the pg_shadow password. (You just leave off the
password field in the secondary file.)

Make toast-table creation and deletion work somewhat reliably.
Don't go through pg_exec_query_dest(), but directly to the execution
routines. Also, extend parameter lists so that there's no need to
change the global setting of allowSystemTableMods, a hack that was
certain to cause trouble in the event of any error.
Move PGPORT envar handling to ResetAllOptions(). Improve long options
parsing to not clobber the optarg string -- so that we can bring
SetOptsFile() up to speed.
Have pg_dumpall write CREATE USER and CREATE GROUP commands instead of raw
COPYs of pg_shadow and pg_group.
It also turns out that pg_dumpall was all but broken for multiple servers
running at non-standard port numbers. You might get the users and groups
from one server and the databases from another. Fixed that.
A little user interface and code cleanup along with that. This also takes
care of the portability bug discussed in "[BUGS] pg_dumpall" in March 2000.

Use a private memory context to store rule information in each relcache
entry that has rules. This allows us to release the rule parsetrees
on relcache flush without needing a working freeObject() routine.
Formerly, the rule trees were leaked permanently at relcache flush.
Also, clean up handling of rule creation and deletion --- there was
not sufficient locking of the relation being modified, and there was
no reliable notification of other backends that a relcache reload
was needed. Also, clean up relcache.c code so that scans of system
tables needed to load a relcache entry are done in the caller's
memory context, not in CacheMemoryContext. This prevents any
un-pfreed memory from those scans from becoming a permanent memory
leak.

Remove freefuncs.c, which hasn't been used in a long time and is not
worth the effort to continue to maintain. Since freeObject() is not
capable of coping with cases like multiple links to a node, it's
unlikely that it ever will be useful again. We now have memory
context management that offers a faster and more reliable way of
getting rid of arbitrary node trees (at the cost of having to know
in advance of building the tree that you'll want to get rid of it).

Makefile cleanup for interface tree. Now essentially with all the

Makefile's and declared the respective variables in Makefile.global.
maintainer-clean target now available at top level, although it does

PL/Perl and Perl interface: the MakeMaker documentation is confusing,
the realclean target *does* "delete derived files", but it also

The submake targets in the various bin directories that update libpq

b) doesn't build the shared library.

First phase of memory management rewrite (see backend/utils/mmgr/README
for details). It doesn't really do that much yet, since there are no
short-term memory contexts in the executor, but the infrastructure is
in place and long-term contexts are handled reasonably. A few long-
standing bugs have been fixed, such as 'VACUUM; anything' in a single
query string crashing. Also, out-of-memory is now considered a
recoverable ERROR, not FATAL.

Second pass over run-time configuration system. Adjust priorities on some
option settings. Sort out SIGHUP vs BACKEND -- there is no total ordering

Removed permissions check on SHOW command.
Add examine_subclass to the game, rename to SQL_inheritance to fit the
official data model better. Adjust documentation.
Standalone backend needs to reset all options before it starts. To
facilitate that, have IsUnderPostmaster be set by the postmaster itself,
don't wait for the magic -p switch.
Also make sure that all environment variables and argv's survive

noname relations. With this change, the 'noname table' support in heap.c
