Can't use Postgres functions

[retendo]

I want to call a function in my Postgres database. I did it like in the example here: https://fsprojects.github.io/SQLProvider//core/programmability.html (I used database provider type POSTGRESQL instead)

But when I want to use it with my dataContext I get

ProductRepo.fs(72, 13): [FS0039] The type 'dataContext' does not define the field, constructor or member 'Functions'.

This is kind of duplicate of #180
