If I wasn't "in the know" I wouldn't associate .pgfoundry.(pgfoundry|postgresql).org with a PostgreSQL related projects by looking at the URL only. As for the "length" of the URL, I think any developer or user of PostgreSQL is knowledgeable enough to take advantage of browser bookmarks. :) I'm definitely against using 'pgfoundry.org' as I believe sub-projects should all fall under the currently used postgresql.org domain. Another thing to think about is search engine placement. Most search engines give higher listings to keywords that are in the domain name. While people will search for 'postgres' and/or 'postgresql' no one is going to come up with 'pgfoundry' on their own. - Frank Wiles <[EMAIL PROTECTED]> http://frank.wiles.org - ---(end of broadcast)--- TIP 3: if posting/reading through Usenet, please send an appropriate subscribe-nomail command to [EMAIL PROTECTED] so that your message can get through to the mailing list cleanly

Subversion has lots of "little" benefits, but nothing that would be a major incentive to switch. The biggest benefits I can think of of the top of my head are: * Commits are actually atomic * protocol sends diffs in both directions which speeds up everything * branching and tagging are cheap constant time operations * the time it takes to make changes is based on the size of the change, not the size of the project * whole directories are versioned not just files. So for example if you for some reason wanted to rename src/backend/bootstrap.c to src/backend/bootup.c you wouldn't lose your revision history information. Same thing goes for complete reorganizations of the file layouts. * You can checkout "parts" of a project so if you need to fix a bug in 7.3.6's src/backend/ you only have to transfer that portion to you. * cvs diff ( well svn diff ) can be done offline. Same with 'status' which shows you your local modifications and 'revert' which reverts your changes back to your last checkout/update/etc. * Revisions numbers are repository wide instead of by file. You can refer to revision #14328 on hackers and everyone knows exactly what you are talking about and can switch their working copies to it easily ( svn switch -r 14328 ). It's sort of like having a tag for every commit made to the repository. It does have some downsides that I have found, most notibly that the size of your sources you have in your working copy are essentially doubled. There is a copy in your .svn directory that allows the offline status, diff, and revert commands to work. - Frank Wiles <[EMAIL PROTECTED]> http://frank.wiles.org - ---(end of broadcast)--- TIP 3: if posting/reading through Usenet, please send an appropriate subscribe-nomail command to [EMAIL PROTECTED] so that your message can get through to the mailing list cleanly

Not to mention highly likely > to confuse people who are used to how it's been set in the past. This may be an unreasonable suggestion, but how about allowing both? I've seen several configuration systems do the following: shared_buffers = 1 ( shared_buffers in pages ) shared_buffers = 100M ( 100 MBs of shared_buffers ) shared_buffers = 2048K ( 2MBs of shared_buffers ) Using something like this would leave the old functionality in tact, allow users to use what they like, and shouldn't introduce that much complexity into the code. - Frank Wiles <[EMAIL PROTECTED]> http://frank.wiles.org - ---(end of broadcast)--- TIP 8: explain analyze is your friend

I don't believe Peter was trying to be rude. And while it isn't a "rule" per se, the more information you can provide in a question the more you increase your chances of someone having an answer for you.

If this is a one time insert you'll want to remove any indexes and rebuild them after the inserts are done.
