Drupal 7.x

Keep getting this error when I try and install Drupal 7. I wanted to do it with Postgres (v8.4.8), but kept getting this error

PDOException: SQLSTATE[42601]: Syntax error: 7 ERROR: syntax error at or near ")" LINE 1: SELECT * FROM menu_router WHERE path IN () ORDER BY fit DESC... ^: SELECT * FROM {menu_router} WHERE path IN () ORDER BY fit DESC LIMIT 1 OFFSET 0; Array ( ) in menu_get_item() (line 445 of /home/pdragon/www/drupal-7.2/includes/menu.inc).

Tried doing it with MySQL (v5.1.41) instead but still getting a similar error

I'm very new to drupal. Most everything is gibberish to me, but I'm learning quick. All I'm looking for is a simple menu that sits next to my content that displays all of the different subcategories to the parent content.

For example, you click my "Cheese" link. You see a short explanation of cheese, and to the left of it you see a menu with several hundred cheeses that link to other information about that cheese.

If you click the "Sausage" link, you see a menu with all the different sausages to the left of that.

I have been tasked with figuring out the best way to transfer the information (book) from a very large website to Drupal. The clients would like update their site but are confused and worried about transferring all the content. The existing site basically has a 2000 page book indexed on it with robust search capabilities.

My question is is Drupal a proper CMS for this task? Can I hire developers for a reasonable price when we have trouble?

Any information or leads will help very much.

Thank you.

I have a Views Slideshow with some basic CSS over it as seen at havoccommunity.net. The problem is that, occasionally, the CSS suddenly appears somewhere else entirely or two slides are on top of each other or the thumbnails disappear behind the main image. This can usually be provoked by reloading the page a few times, go from one page to the frontpage or just generally load up the site.

Hi,
How can I style some classes to custom fields in D7?
I have created few image fields and I got something like this:
<div class="field-item even" rel="og:image rdfs:seeAlso" resource="path"><img typeof="foaf:Image" src="path" alt="" /></div>

how do i add an edit tab to a custom theme made via panels and precision? i see it in many themes i just want to add it to the User menu on my site.
