Pass a URI as a pgAdmin parameter

[Clodoaldo Neto <clodoaldo.pinto.neto@xxxxxxxxx>]

I can connect to Heroku with psql passing a URI as generated by http://api.postgression.com:

$ psql postgres://hcnkrxukvhqiww:LryFxzcmlBoYtGtXPsvlA8H9sI@xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx:5432/dearu2qcqcmi7t

I want to do the same with pgAdmin:

$ pgadmin3 -qc postgres://hcnkrxukvhqiww:LryFxzcmlBoYtGtXPsvlA8H9sI@xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx:5432/dearu2qcqcmi7t

but I get the error message:

Unknown token in connection string: <the passed string>

Is it possible to pass a URI as parameter to pgAdmin? Fedora 21, pgadmin3_94.x86_64 1.20.0-2.f21 from pgdg-94-fedora.repo
