Greenplum has contributed both code and money in the past. They don't
look likely to do so this year, but they haven't said they won't either.

You missed Yahoo in the list of derivatives. They've contributed money
to pgCon, and are discussing contributing code. One of the other DW
companies is meeting me on Tuesday to talk about contributing something
unspecified; more when we do a PR. Netezza has not contributed anything
to date.
