Of the above, Greenplum is the only one that has a working relationship with
the postgresql community.
BTW, does this mean you confirmed Aster is based on postgres? I've not seen
any public evidence of that so far, so would be curious to see some.

Hard to say... it is really in a companies best interested to keep thier
codebase close to postgres's if possible (though it certainly takes some
effort). Since they didn't contribute to postgres back when they were
starting out though, code drift isn't neccessarily a given; it's more that
they see postgres and thier code as "secret sauce" that they'd rather others
didnt know about.
