While installing postgresql-9.4, I noticed that the deb does not offer a `Provides: postgresql`. I believe the convention for the comparable rpm builds is to offer a virtual provides so that any packages requiring the `postgresql` server capability continue to function after installing postgresql-9.4, but removing the Ubuntu-packaged `postgresql` package.
It seems this convention was followed for the postgresql-client-9.4 as it offers the following virtual Provides:
Provides: postgresql-client
Any reason not to add the following virtual provides to the `control` file for the postgresql-9.4 deb package?
