Hello Adminer,
PostgreSQL is not that much difficult - or at least not more difficult than MySQL. Of course if by "NASA software" you mean "command line", then indeed, postgresql require to type a few commands here and there (unless using PgAdmin).
Creating a user should be as simple as this:
CREATE USER elibsrv WITH PASSWORD 'mypass';
PostgreSQL comes with an extensive documentation:
http://www.postgresql.org/docs/8.4/s...reaterole.html
You might want to look into the readme.txt file of elibsrv - I wrote there the few commands that would be required to declare a db for elibsrv on PostgreSQL.
If you have troubles with something specific, don't hesitate to ask - I will try to help out (and this could give me some ideas to document the whole thing better).
Anyway, as said before, I know that there are people out there that are more confident with MySQL, and I will see what I can do to make elibsrv run on MySQL.
As for flat files - of course flat files are cool and all, but I just don't have the time to reinvent a db engine on my own.
