c3e9699f21 Enable IPv6 connections to the server, and add pg_hba.conf IPv6 entries
if the OS supports it.  Code will still compile on non-IPv6-aware
machines (feature added by Bruce).

8fc86dd593 We have just finished porting the old KAME IPv6 patch over to
postgresql version 7.3, but yea... this patch adds full IPv6
support to postgres. I've tested it out on 7.2.3 and has
been running perfectly stable.

72a3902a66 Create an internal semaphore API that is not tied to SysV semaphores.
As proof of concept, provide an alternate implementation based on POSIX
semaphores.  Also push the SysV shared-memory implementation into a
separate file so that it can be replaced conveniently.

36f693ec69 Further work on elog cleanup: fix some bogosities in elog's logic about
when to send what to which, prevent recursion by introducing new COMMERROR
elog level for client-communication problems, get rid of direct writes
to stderr in backend/libpq files, prevent non-error elogs from going to
client during the authentication cycle.

a033daf566 Commit to match discussed elog() changes. Only update is that LOG is
now just below FATAL in server_min_messages.  Added more text to
highlight ordering difference between it and client_min_messages.

---------------------------------------------------------------------------

REALLYFATAL => PANIC
STOP => PANIC
New INFO level the prints to client by default
New LOG level the prints to server log by default
Cause VACUUM information to print only to the client
NOTICE => INFO where purely information messages are sent
DEBUG => LOG for purely server status messages
DEBUG removed, kept as backward compatible
DEBUG5, DEBUG4, DEBUG3, DEBUG2, DEBUG1 added
DebugLvl removed in favor of new DEBUG[1-5] symbols
New server_min_messages GUC parameter with values:
        DEBUG[5-1], INFO, NOTICE, ERROR, LOG, FATAL, PANIC
New client_min_messages GUC parameter with values:
        DEBUG[5-1], LOG, INFO, NOTICE, ERROR, FATAL, PANIC
Server startup now logged with LOG instead of DEBUG
Remove debug_level GUC parameter
elog() numbers now start at 10
Add test to print error message if older elog() values are passed to elog()
Bootstrap mode now has a -d that requires an argument, like postmaster

aed378e8d1 Fix authentication so that it doesn't record an extra 'Password
authentication failed' and a 'send() failed: Broken pipe' message
on every connection from psql in password auth mode.  Problem is
that psql doesn't ask user for a password until it sees a password
challenge failure, and libpq just closes the connection unceremoniously
if it's challenged for a password when it hasn't got one to send.
Accordingly, EOF from the client after asking for a password is
normal behavior and should not result in postmaster log entries.

See attached revised patch. (I'm sure the configure.in stuff can be done
right/better, I'm just not enough of a autoconf guru to know what to
change it to.)

Peter Eisentraut
9b4bfbdc2c Handle reading of startup packet and authentication exchange after forking
a new postmaster child process.  This should eliminate problems with
authentication blocking (e.g., ident, SSL init) and also reduce problems
with the accept queue filling up under heavy load.

The option to send elog output to a different file per backend (postgres -o)
has been disabled for now because the initialization would have to happen
in a different order and it's not clear we want to keep this anyway.

a27b691e29 Ensure that all uses of <ctype.h> functions are applied to unsigned-char
values, whether the local char type is signed or not.  This is necessary
for portability.  Per discussion on pghackers around 9/16/00.

996832caee Make the location of the Kerberos server key file run time configurable
(rather than compile time). For libpq, even when Kerberos support is
compiled in, the default user name should still fall back to geteuid()
if it can't be determined via the Kerberos system.

A couple of fixes for string type configuration parameters, now that there
is one.

554e56e628 Expand secondary password file feature, so that you can use these

but can still use the pg_shadow password. (You just leave off the
password field in the secondary file.)
