In the spirit of sportsman-like conduct, I ++'ed your post. Mostly the reason I venture to ask this question here is because it's a reasonable forum with intelligent persons of moderate tempers. ;) I don't get along with usenet very well, some IRC channels seem to smack of elitism, and don't know of any other online forums that would be better suited to answer my question.
Anyhow, to answer your question, I was hoping to get one row per distinct doc_num whose version was the max() of all versions for that doc_num, and whose title corresponded to the record with the max version:
title | doc_num | version
-------+---------+--------
foo | 1234 | 2
baz | 5678 | 1
Compare my chart above to the "original" and you may see what I mean.
Anyhow, my apologies for tempting fate in this manner. If I've overstepped my bounds by replying to your post, I once again apologize. But if you find the breath to chastize me once more, I also welcome links to any Database-related forums. ;)

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
