Re: GOODS - a sensational public domain database backend - Mailing list pgsql-hackers

Kostya is a good qualified programmer. I know him and he is always open for
challenges. Some time ago, me and Teodor ask him about GiST support
in his another database (Gigabase). It was sort of challenge ( we wanted
to port our contrib/tsearch module ) and he did that (using libgist).
We work with gigabase database embedded into our application under
Windows (we had a lot of troubles with perforance of postgresql under
Cygwin:-) and quite happy.
