I have this patch for pgmodeler

https://www.pgmodeler.com.br/

It builds.

I would say that 20% of the work is done, now the remaining 80% is
integration work

It has some somewhat bizarre runtime requirements and procedures, it
probably needs some search paths to be set and probably a desktop file
should be written

I'm not keen to see after this stuff

So, I post it here, I'd be glad if anyone is willing to chip in some bits
and pieces

Thanks

P.S. I'm not sure if Potluck could cover this use case, but  I was thinking
that maybe a guix-wip mailing list like the guix-patches one could be
useful for half baked things like this
