Actually that's Rob Sargent you're quoting. Adrian took issue with that
statement, as do I. While Google isn't finding me anything that says
"Yes, you can sell Postgresql," here are a few points:

- Point to anything in the license wording that says you can't charge
money to distribute Postgresql. You can't.

- Even software licensed under the GPL, which is a considerably more
restrictive license, can be sold. The free software folks consider the
right to sell as one of the freedoms associated with free software. [1]

- The Postgresql license page says it is "a liberal Open Source license,
similar to the BSD or MIT licenses." [2] The MIT license itself explicitly
states that it grants rights to "sell copies of the software."

Cheers,
Ken
