Re: warning: pg_query(): Query failed

hi steven,

here's another file where the actual SQL query (the one in the error
message) is defined. it's in the forum_get_forums() function. bruno
noticed that the IF (via pl/pgsql) might not like the boolean casting
to "2" since 7.4 is more strict about casting? does this help?

<h3>Creating a forum</h3>
<p>The forum module uses taxonomy to organize itself. To create a
forum you first have to create a <a href=\"%taxonomy\">taxonomy
vocabulary</a>. When doing this, choose a sensible name for it (such as
\"fora\") and make sure under \"Types\" that \"forum\" is selected.
Once you have done this, <a href=\"%taxo-terms\">add some terms</a> to
it. Each term will become a forum. If you fill in the description
field, users will be given additional information about the forum on
the main forum page. For example: \"troubleshooting\" - \"Please ask
your questions here.\"</p>
<p>When you are happy with your vocabulary, go to <a
href=\"%forums\">administer &raquo; settings &raquo; forum</a> and set
<strong>Forum vocabulary</strong> to the one you have just created.
There will now be fora active on the site. For users to access them
they must have the \"access content\" <a
href=\"%permission\">permission</a> and to create a topic they must
have the \"create forum topics\" <a
href=\"%permission\">permission</a>. These permissions can be set in
the <a href=\"%permission\">permission</a> pages.</p>
<h4>Icons</h4>
<p>To disable icons, set the icon path as blank in <a
href=\"%forums\">administer &raquo; settings &raquo; forum</a>.</p>

may use images of whatever size you wish, but it is recommended to use
