From (guix)Synopses and Descriptions:

Please avoid marketing phrases such as “world-leading”,
“industrial-strength”, and “next-generation”, and avoid superlatives
like “the most advanced”—they are not helpful to users looking for a
package and may even sound suspicious.  Instead, try to be factual,
mentioning use cases and features.

Here, ‘most popular’ would could as marketing (it isn't important
whether it's popular, what is important is that it works well),
and to a lesser degree ‘efficient and secure’ -- everything is
supposed to be efficient and secure (with varying success).

Greetings,
Maxime.

Hello Maxime,

I've just copy-pasted the author's description as in:

  https://pypi.org/project/psycopg2-binary/

So, if I understand correctly, package contributors should (re)write
packages descriptions?

Yes, package descriptions from upstream are useful but may need to
be rewritten a bit.

Also, for whatever reason, people seem to always ignore the copyright
and license on upstream's description, but I don't understand how this
would be justified legally.

Greetings,
Maxime.

This needs to be documented ...

... here, as a comment, to aid future readers, and to avoid
accidentally teaching people to just disable tests.

Maxime.

`(#:tests? #f)' because tests require a live PostegreSQL instance.

Maxime's suggestions are taken into account in this patch:
  - `(#:tests? #f)' is commented in the code
  - superlatives in the description have been removed

Applied with minor tweaks to the synopsis and description and a commit
log that follows our conventions:

Thanks, and thank you Maxime!
