Interface FunSQL with LibPQ using DBInterface

General Usage
4

Now that I have the database open and can interact with it, I am having problems closing the Database. I am not sure where to go from here.

julia> close(conn)
ERROR: MethodError: no method matching close(::FunSQL.SQLConnection{LibPQ.Connection})

or 

julia> DBInterface.close(conn)
ERROR: MethodError: no method matching close(::FunSQL.SQLConnection{LibPQ.Connection})

or 

julia> DBInterface.close!(conn)
ERROR: MethodError: no method matching close!(::LibPQ.Connection)
