Installing Drupal

Fails on the last line. Here's the output:
ERROR: language "plpgsql" does not exist

Is there something that has to be set on the server for new accounts to be generated correctly? When creating a new account, I get the following error:

warning: mail() [function.mail]: Failed to connect to mailserver at "mail.host" port 25, verify your "SMTP" and "smtp_port" setting in php.ini or use ini_set() in D:\oghs\intranet\modules\user.module on line 257.

I figure it is a server issue because I had a Drupal site hosted on a previous server and working fine. When I moved it to its current server, I started getting this problem. Any ideas--anyone--anyone--Bueller?

I'm working on some theme stuff, and wanted to know if it's possible to test for the condition if Right or Left menu blocks exist to be rendered. Basically, just want to check if any blocks are active, and set to be on the Left or Right side. I searched the site, but didn't easily come up with anything I plugged in. I've been pouring through other themes, for an example, but again didn't find anything.

I am trying to customize my blocks. There is an "admin preview" and it shows 3 layout schemes, but it turns out all blocks are on the "right" even if I explicitly define some of them to be on the left.

How can use the right schemes?

I am using drupal 4.1.0

Its still the old Question with the table prefixes. Seems that there Is no real solution for this ?

what is about this Project with this script which makes it possible to make prefixes. There where some comments about some problems with it...
is there any solution for that ?
Does that Work ?
Has anyone tried it out ?

[note: the 'magic_quotes_gpc = 0' requirement was removed in Drupal 4.4]

I'm trying out drupal on a managed host, which has magic_quotes_gpc = 1 globally. I've tried to set this variable locally with "ini_set( "magic_quotes_gpc", 0);" in common.inc, but drupal still complains at the top of every page.
