Great find, Daniele! That appears to be true for GPLv3 but not LGPLv3 which is included on the Category X list. (Have to love how complex licenses can get!)
From the Apache FAQs:
- Apache takes a strong approach against distributing any components under prohibited licenses (i.e. Category X), which includes LGPL. Therefore, we cannot even use LGPL licenses open source in the project. This appears to be regardless of linking.
- While Apache projects cannot distribute Category X components within their releases, a project can provide the user with instructions on how to obtain and install the non-included work if the component is only needed for optional features. In this case, optional means that the component is not required for standard use of the product or for the product to achieve a desirable level of quality. They recommend you ask, “will the majority of users want to use my product without adding the optional components?” In our case, it would not fit Apache’s definition of “optional.”
Unfortunately, GPLv3 license would require us to release the entire project as GPLv3 vs the other options that can be incorporated into an Apache project while keeping the project under the Apache license. (https://www.apache.org/legal/resolved.html#category-a and https://www.apache.org/legal/resolved.html#category-b).
I really appreciate the dialogue as we work on understanding the options and thanks for the tip on cross posting! I didn’t include pgsql-general on this response.
Best,
Jamie

Is this true? this page leads to
<http://www.apache.org/licenses/GPL-compatibility.html>, which says:
"""
This licensing incompatibility applies only when some Apache project
software becomes a derivative work of some GPLv3 software, because
then the Apache software would have to be distributed under GPLv3.
This would be incompatible with ASF's requirement that all Apache
software must be distributed under the Apache License 2.0.
"""
Is your work a "derivative" of psycopg, or it merely uses psycopg? If
you only want to use it you should be fine.

P.S. certain Postgres mailing list don't tolerate cross-posting. I
don't know about pgsql-general, but I would avoid it anyway.
