Re: [DOCS] Docbook 5.x

Here is the final patch set for the conversion.

Great!

I have some questions.
1. Can you share the exact scripts you use to generate 0002?
(We transform the documentation to xml since 9.6 on-fly so it would be nice to adjust our scripts for previous versions too.)
2. Will you rename *.sgml to *.xml and move src/sgml to src/xml?
3. And I still think that hard-coding references and replacements in the standalone-profile is not good. Are you going to apply less hackish approach?
(See https://www.postgresql.org/message-id/b4fd6932-8d44-3210-48ab-bbc393bf9a23%40gmail.com , patches/xml/installation.patch and patches/xml/installation-single.xsl)
4. BTW, when making postgres-A4.pdf, I get
[WARN] FOUserAgent - Destination: Unresolved ID reference "ecpg-type-timestamp-date" found.
It can be fixed by moving the id from the title tag to sect4:
-    <sect4>
-     <title id="ecpg-type-timestamp-date">timestamp, date</title>
+    <sect4 id="ecpg-type-timestamp-date">
+     <title>timestamp, date</title>
I wonder, what were the reasons to set id for the title tag?
