The <note> element contains a license remark, the <meta> element a timestamp. Both are in the beginning of the file. You could simply remove them with a text editor.

It is a little bit surprising to me because the osm2pgsql version I tried had happily ignored the extra elements.

The rationale behind these two elements (and a third element <error> appearing only in case of an error) is to provide useful information in additional tags. This allows any tool to safely just ignore tags which it doesn't know. The license remark is a matter of good style - nobody should say he didn't know about the license of the excerpt. And the timestamp can enable editors like JOSM with the mirrored_download plugin to decide whether a given set of data is outdated or not.

Cheers,

Roland
