  1. too many users for postgresql? :)

    Will Trillich <will@serensoft.com> — 2003-01-27T05:46:06Z

    so there i was, minding my own business, browsing around, and at
the postgresql.org site today i got--

	Warning: pg_connect() unable to connect to PostgreSQL
	server: FATAL 1: Sorry, too many clients already in
	/usr/local/www/www.postgresql.org/idocs/opendb.php on line 3
	Unable to access database

1) that speaks well for the future of postgresql because there
are enough people interested and browsing that they overran the
current parameters. probably not hard to fix the postgresql end
on this.

2) it gives out lots more information than necessary -- now i
know where the docs are... maybe some php parameters need some
tweaking, eh?

Hi Will,

Which page(s) were you at to get this?  Have been trying to temporarily 
disable database access from parts of the site to stop this error until 
the max_connections parameter is bumped up.  Looked like all the pages 
haven't been fixed yet.

:-(

Regards and best wishes,

Justin Clift

the specific page i was after was

	http://www.postgresql.org/idocs/index.php?xfunc-plhandler.html

so apparently <docroot>/index.php called (either directly or
through other modules) opendb.php which is where the trouble
arose.

no big deal for me -- i had more serious issues trying to get my
own server re-started after adding another hard drive with bad
parameters (which locked everything up so bad i quite nearly had
a nervous breakdown. thank goodness i thought to try
clarkconnect's rescue_ide boot on their install cd. everything
came back up after a few fsck's and a revisit to the autodetect
in bios... whew! very nearly had to call the men in white coats!)

and just now (Mon Jan 27 01:05:28 CST 2003) at the root level of
the postgresql.org website, i see lots of

	"temporarily unavailable"

under 'news' and 'events'... maybe i just happened to hit the
vacuum or dump cron job?

This is one of the biggest advantages to the pooled model of AOLserver.  If 
you have the number of connections to the database set equal to the number of 
connection threads, you can never get this sort of message.  The webserver 
will refuse the connection first -- which is probably a better thing to do, 
rather than give such a damaging ('What? PostgreSQL can't scale to the load 
of its own server?') error message.  While you certainly can do this with 
Apache/PHP, it requires a much larger number to make it work well under load.

As there's no robots.txt file, ( http://www.postgresql.org/robots.txt => 
404) it could just be a spider/crawler (e.g. google) hitting the site with 
many connections at once.

If that is an issue, I would suggest letting google et all, spider the 
static docs, and disallowing them from the dynamic idocs. However this 
would mean useful suggestions in the idocs won't turn up in google etc.

good point. the webmaster(s) can check their logs to see what it
was that spiked it yesterday.

maybe have a different "driver" return idocs for known spiders
(base content-spewed on user-agent); there's gotta be a way to
have both search-engine-able idocs and enough connections to
keep it open for the human browsers...

If the robots are well behaved you can control things through robots.txt.
If they are evil robots, you need to have something that limits request
rates for a single IP address (or maybe a /24).
