capabilities of specifying time zones as intervals per SQL9x.
Put refentrytitle contents on the same line as the tag.
 Otherwise, leading whitespace is propagated into the product, which
 (at least) messes up the ToC layout.
Remove (some) docinfo tags containing dates. Best to omit if the dates
 are not accurate; maybe use CVS dates instead or leave them out.

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

 between Postgres and PostgreSQL.

I hope all the dust has settled out now ...

IPC key assignment will now work correctly even when multiple postmasters
are using same logical port number (which is possible given -k switch).
There is only one shared-mem segment per postmaster now, not 3.
Rip out broken code for non-TAS case in bufmgr and xlog, substitute a
complete S_LOCK emulation using semaphores in spin.c.  TAS and non-TAS
logic is now exactly the same.
When deadlock is detected, "Deadlock detected" is now the elog(ERROR)
message, rather than a NOTICE that comes out before an unhelpful ERROR.

hosting product, on both shared and dedicated machines.  We currently
offer Oracle and MySQL, and it would be a nice middle-ground.
However, as shipped, PostgreSQL lacks the following features we need
that MySQL has:

1. The ability to listen only on a particular IP address.  Each
   hosting customer has their own IP address, on which all of their
   servers (http, ftp, real media, etc.) run.
2. The ability to place the Unix-domain socket in a mode 700 directory.
   This allows us to automatically create an empty database, with an
   empty DBA password, for new or upgrading customers without having
   to interactively set a DBA password and communicate it to (or from)
   the customer.  This in turn cuts down our install and upgrade times.
3. The ability to connect to the Unix-domain socket from within a
   change-rooted environment.  We run CGI programs chrooted to the
   user's home directory, which is another reason why we need to be
   able to specify where the Unix-domain socket is, instead of /tmp.
4. The ability to, if run as root, open a pid file in /var/run as
   root, and then setuid to the desired user.  (mysqld -u can almost
   do this; I had to patch it, too).

The patch below fixes problem 1-3.  I plan to address #4, also, but
haven't done so yet.  These diffs are big enough that they should give
the PG development team something to think about in the meantime :-)
Also, I'm about to leave for 2 weeks' vacation, so I thought I'd get
out what I have, which works (for the problems it tackles), now.

With these changes, we can set up and run PostgreSQL with scripts the
same way we can with apache or proftpd or mysql.

In summary, this patch makes the following enhancements:

1. Adds an environment variable PGUNIXSOCKET, analogous to MYSQL_UNIX_PORT,
   and command line options -k --unix-socket to the relevant programs.
2. Adds a -h option to postmaster to set the hostname or IP address to
   listen on instead of the default INADDR_ANY.
3. Extends some library interfaces to support the above.
4. Fixes a few memory leaks in PQconnectdb().

The default behavior is unchanged from stock 7.0.2; if you don't use
any of these new features, they don't change the operation.

Fix misspelling of disbursion to dispersion.

 <term> not allowed in paragraphs; <option> is a better choice.

up debugging options for postmaster and postgres programs.  postmaster
-d is no longer optional.  Documentation updates.

Add new pages for programming languages and tcl shells.

ecpg reference page still needs formatting.

No big deal; fixed lots of other markup at the same time.
Bigest change: make sure there is no whitespace
 in front of <term> contents.
This will probably help the other output types too.

postgres-ref.sgml is not yet marked up.
