This leaves the MySQL password in the output of ps. The same is true in the case of the environment variable used for postgres.

If this is a concern, you develop in a strange place and have bigger problems. That said, patches are welcome :)

in the case of cross-referenced environnements (or just environnement aliases) like:

all:
adapter: postgresql

development: all
database: dev
login: …
pass: …

production: all
database: prod
login: …
pass: …

Error “not supported for this database type” is returned. Environnement should be built correctly
