If primary key is not an integer, inserting items fails

Describe the bug When setting the PRIMARY KEY as something other than the default INTEGER, INSERTs fail. For example:

In the db/migrations/*_create_table_users.jl up() function,

function up()
    create_table(:users) do
        [
            column(:id, :string, "PRIMARY KEY")
            column(:name, :string)
        ]
    end

    add_index(:users, :id)
    add_index(:users, :name)
end

And in an example app/resources/users/Users.jl file,

module Users

using SearchLight
using Genie.Sessions

export User

mutable Struct User <: Abstract Model
    ### INTERNALS
    _table_name::String
    _id::String

    ### FIELDS
    id::DbId
    name::String
end

### CONSTRUCTOR
User(;
    ### FIELDS
    id = Sessions.id(), # Genie.Sessions.id() returns a session id string
    name = ""
    ) = User ("users", "id", id, name)

function seed()
    CurrentUsers = [
        ("sarah"),
        ("evelyn")
    ]

    for u in CurrentUsers
         User(name = u[1]) |> SearchLight.save!
    end
end

The error appears to be occurring HERE because the data type of the primary key is not checked, is assumed to be an integer, and hence when it is not an integer, the value is not escaped and the "unrecognized token" error is thrown.

To reproduce See above.

Expected behavior The data type of the primary key should be checked and the query should be made according to the datatype, e.g. the id should be escaped if the data type is string.
