RIght. The counter-argument is that if we just do that, then what will
likely happen is that people who buy PostgreSQL services from
Microsoft, Amazon, EDB, Crunchy, etc. will end up with reasonable
options in this area, and people who download the source code from the
Internet probably won't. As an open-source project, we might hope to
avoid a scenario where it doesn't work unless you buy something. On
the third hand, half a loaf is better than nothing.
