IMNSHO, having commercial solutions based on postgresql which extend
postgres in directions not (yet?) done by core postgres is nothing to be
ashamed of.

And we should at least mention the OSS version of Bizgres as a place
where quite a lot of initial development is done on performance
improvements considered too risky for mainline postgresql.

And if you need a more technical reason, you can use free libpq and psql
to connect to even Bizgres MPP ;)
