Subject: [HACKERS] auth.c for kerberos.

  I made pgsql with eBones(international version of Kerberos4).  The
following modification was needed.  And I added read permition for
group to srvtab instead of running postmaster as root.

By: Dan McGuirk <mcguirk@indirect.com>

According to man page under FreeBSD for sys_errlist[], strerror() should be
used instead...not sure if this will break other systems, so only changing
two files for now, and we'll see what "errors" it turns up

    of common routines in pqcomprim.c (pq communication primitives).
    Not all adapted to it yet, but it's a start.

  - Rewritten some of those routines, to write/read bigger chunks of
    data, precomputing stuff in buffers instead of sending out byte
    by byte.

  - As a consequence, I need to know the endianness of the machine.
    Currently I rely on getting it from machine/endian.h, but this
    may not be available everywhere? (Who the hell thought it was
    a good idea to pass integers to the backend the other way around
    than the normal network byte order? *argl*)

  - Libpq looks in the environment for magic variables, and upon
    establishing a connection to the backend, sends it queries
    of the form "SET var_name TO 'var_value'". This needs a change
    in the backend parser (Mr. Parser, are you there? :)

  - Currently it looks for two Env-Vars, namely PG_DATEFORMAT
    and PG_FLOATFORMAT. What else makes sense? PG_TIMEFORMAT?
    PG_TIMEZONE?

Subject: [HACKERS] Patches for 970316 compilation

I made a small pre-emptive change in the new datetime code to eliminate
calls to infnan(). Hopefully this will make Solaris (and probably other
non-GNUlib) systems happier. Didn't find fe-connect.h in the 970316
distribution, so made one up. Also, one of the test routines needs an
update for the geo-decls.h -> geo_decls.h name change.
Patches appear below...

Subject: [HACKERS] Patch for io routines

  I am currently trying to improve on the front-backend communication
routines; and noticed that lots of code are duplicated for libpq and
the backend. This is a first patch that tries to share code between
the two, more to follow.

        mjl

properly...

Add new "overloaded" oracle_compat functions (see man oracle_compat)

Subject: [HACKERS] lock debug trace

This is an update to my previous patches for lock debugging, already applied
to the current sources. It adds some improvements in the output messages and
some more output in WaitOnLock(). I have used with success to trace a nasty
deadlock condition on pg_listener.

Just noticed that the psql man page is missing the -T option for specifying
HTML table options.

> Please apply them to the direcory "backend/optimizer/geqo".
> Two new files with different crossover techniques are included.
> Standard procedure is optimization by means of "geqo_erx.c"

Subject: [HACKERS] timestamp type

OK, last one.  This patch adds an ANSI SQL 'timestamp' type.

Subject: [HACKERS] password authentication

This patch adds support for plaintext password authentication.  To use
it, you add a line like

host         all         0.0.0.0       0.0.0.0           password  pg_pwd.conf


to your pg_hba.conf, where 'pg_pwd.conf' is the name of a file containing
the usernames and password hashes in the format of the first two fields
of a Unix /etc/passwd file.  (Of course, you can use a specific database
name or IP instead.)

Then, to connect with a password through libpq, you use the PQconnectdb()
function, specifying the "password=" tag in the connect string and also
adding the tag "authtype=password".

I also added a command-line switch '-u' to psql that tells it to prompt
for a username and password and use password authentication.

Subject: [HACKERS] linux/alpha patches

These patches lay the groundwork for a Linux/Alpha port.  The port doesn't
actually work unless you tweak the linker to put all the pointers in the
first 32 bits of the address space, but it's at least a start.  It
implements the test-and-set instruction in Alpha assembly, and also fixes
a lot of pointer-to-integer conversions, which is probably good anyway.

Subject: [HACKERS] equal column and table name patch

This fixes a bug where selects fail when there is a column with the same
name as the table it's a part of.

Subject: [HACKERS] better access control error messages

This patch replaces the 'no such class or insufficient privilege' with
distinct error messages that tell you whether the table really doesn't
exist or whether access was denied.
