Keep up the good work
Nice to see more utilization of PostgreSQL.
In my experience it is one of the best free/opensrc
databases out there.
Just my 2 cents
TeXmacs exists, if nothing else, in it's own right.
I've used Tex for a long time, and occasionally
MS Word, StarOffice, etc., and TeXmacs is a fine
project on typesetting.
Please keep up the good work.
