Re: Postgres Licensing - Mailing list pgsql-hackers

You seem to be working for EnterpriseDB, which is a company specializing on postgres. So how does EnterpriseDB sell the
advancedserver? By modifying it, I guess! So that is something similar I want to do. Getting a few dollars for some
hardwork is not bad for me. Plus I love to find new things, so it would be fun as well. <br /><br />I would surely
includethe PostgreSQL licence in the product (if I get successful to) and sell it to a few peopl who are looking for
somespecific features and are pissed off with the great MySQL.<br /><br />Thanks to both DAVE and Heikki :)<br /><br

Doesthe license restrict me from adding my closed source additions to<br /> the project and then sell the product? I
wantto add in a few files here and<br /> there which would be closed source in nature, while all the changes made to<br

mixproprietary code with the PostgreSQL sources, and sell or distribute for free the combined product with or without
sources.The only requirement of the PostgreSQL license is that all copies must include the copyright notices and the
licensetext.<br /><br /> (Disclaimer: I am not a lawyer)<br /><font color="#888888"><br /> -- <br />  Heikki
