postgresql:link can only connect same-named apps and dbs

[piranha]

Or I expect something which I shouldn't. I expected that dokku postgresql:link appname dbname will connect a database to an app, but looking at sources what it does is rather strange: it checks $3 once, but then uses $APP for everything else, so that $3 is effectively discarded.

Is this a bug or it works as intended and I just don't understand something?

i think it's typo.
I changed locally and everything works fine.

I guess so, it also works for me when I changed it.
