DocBook 5.2 is published [1] [2].

This mail contains a new version of the PostgreSQL migration scripts
(DocBook 4.5 format to 5.2 format). They are developed for PG versions
13 up to 17. Please see README.md for details. The generated output
looks good at first glance, but: a) I don't have an idea how to
guarantee that it looks REALLY identical at ALL places. Everyone is
invited to search differences. b) pdf (resp. 'fo') cannot be generated.
It seems to be a performance issue - a small number of test-pages works
well. *Concerning this issue I need help from someone with good xslt
knowledge.* c) On my laptop epub cannot be generated (for version 4.5 as
well as for 5.2). dbtoepub is a ruby program.

Development and testing was done only at an Ubuntu 22.04 laptop. For
those who want to see the results quickly, download [3] (converted sgml,
html, and man files, 8MB) or [4] (plus postgres-full.xml, postgres.txt,
html single page, 16 MB). The two files remain online for some days.
