[GENERAL] Re: PostgreSQL 8.3 XML parser seems not to recognize the DOCTYPE element in XML files

Is any form of DOCTYPE accepted?

We're getting errors on a second line in an XML document that
starts like this:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE DOT_OFFICER_CITATION SYSTEM "http://host.domain/dtd/dotdisposition0_02.dtd">

The actual host.domain value is resolved by DNS,
and wget of the url works on the server running PostgreSQL.
Attempts to cast the document to type xml give:

ERROR: invalid XML content
DETAIL: Entity: line 2: parser error : StartTag: invalid element name
<!DOCTYPE DOT_OFFICER_CITATION SYSTEM "http://host.domain/dtd/dot
^

It would be nice to use the xml type, but we always have DOCTYPE.
I understand that PostgreSQL won't validate against the specified
DOCTYPE, but it shouldn't error out on it, either.
