IMHO clues like:
"What versions of the databases did you use?
- PostgreSQL - 7.0 release version
- Proprietary 1 - 8.1.5
- Proprietary 2 - 7.0
- MySQL - 3.22.32
- Interbase - 6.0
"
and
"PostgreSQL" and "Proprietary 1" was running "red hat linux 6.1" and
"Proprietary 2" was running Windows NT server 4 - service pack 4"
in articles like this one: http://www.xperts.com/news/press1.htm
helped some people narrow it down a bit. :)
