Обсуждение: PostgreSQL and XML
PostgreSQL users working with XML may be interested in my post at: http://www.throwingbeans.org/tech/postgresql_and_xml.html It explains the work I did with John Gray to enable XPath in SQL queries against XML stored in Postgres text columns; my company is now using this functionality in several large-scale implementations. As far as I know, this represents the most complete XML support of any open source RDBMS. I'll be very pleased to receive any questions or suggestions!

Wow, what is it with you guys and your unsupported assertions against PHP today. First on hackers and now on general. You don't PHP, don't use it. You want the website done in JSP, then do it and quit bitching about someone else's choice of tools. It's not failing because of a PHP error. did you look at the screen? It's failing because the database isn't answering. JSP wouldn't make it any better, it would still be offline. My PHP server stays up 24/7 under heavy load doing very complex things. One machine, 99.99% uptime, no unscheduled downtime in two years. Our JSP Server farm has failures every week, where some part of the complex inner workings that is JSP fail for no apparent reason and needs to be reset. That's enterprise computing? If it wasn't a failover of three machines it would be offline for an hour or so a week. I've seen as many unsupported assertions that "postgresql is a toy, use oracle" before. They're just as ugly no matter what you're talking about. PHP works a charm, and if you'd actually try and benchmark it against JSP you might be surprised how much faster it is, especially under load. Informed opinion is welcomed, but this kind of off the cuff slamming of something you know so little about it just ugly.
I have to agree here. I use php on a site that gets 13,000,000 hits a day, and has 1,600,000 visitors. I don't have any problems. It's a solid well development system, and all it takes is to configure the postgres daemon to accept as many connections as your webserver can handle. No need to bash any language, each has their own niche, just as DBMS's do.

Tongue in cheek Friday nonsense OK. I don't like or use PHP for personal reasons but it was just a bit of end of week fun in very bad taste. It is called unwinding. No harm meant. No harm felt?

BTW Awesome work, would love to see this included in upcoming releases.

No harm felt? It's ok, but it gets real old when, after a year or two, you constantly hear how PHP is crap and JSP is the only way to go, when the people saying it are in the marketing or sales department and wouldn't know java or php code if it bit them on the buttocks. Yet, they parrot this stale old stuff over and over, and eventually, they really do start to affect policy decisions based on emotion rather than logic. Being of Vulcan descent, this bugs me to no end. Plus, do you really want all the PHP folks to stick to MySQL and never learn Postgresql? PHP may well be your biggest potential market. If a new PHP developer is reading this list, he may well have headed over to MySQL to see what it has to offer, since he's not gonna feel very welcome here.
