New document needs markup work

Stefan Simkovics wrote a Master's Thesis on some modifications to
Postgres. He has donated the text (and the mods) to the project, and all
of it should eventually end up integrated into the formal documentation.

The thesis contains very nice introductory sections on SQL, and I have
committed those to a file doc/src/sgml/sql.sgml for eventual inclusion
in the User's Guide, but have not completed the markup.

Is anyone interested in working on this document? It currently is marked
up in latex, and needs to be converted to sgml. The conversion should
not be difficult, but will take a bit of time to work through (a few
hours? Maybe less). Some help would be greatly appreciated.

TIA
