Dapper.Contrib character case bug

Hi!
I have table in postgres created with field names in quotes (i.e. case sensitive):

create table "buttons" (
"Id" SERIAL PRIMARY KEY,
"UserId"  INTEGER,
"Phone"  VARCHAR,
"NumberType" INTEGER,
...

and c# class also with case sensitive properties:

    public class Button
    {
        public Int32 Id { get; set; }
        public Int32 UserId { get; set; }
        public String Phone { get; set; }
        public NumberType NumberType { get; set; }
        ...

When I try to insert record with InsertAsync, it throws an error

42703: column "id" does not exist

as you can see, column "id" is written here in lower case, because the function InsertAsync skips id-column during query creation.

UpdateAsync works perfectly because it uses "Id" in where clause.

But when I change the name of column in database to "id" - InsertAsync works good, but UpdateAsync fails by the same reason.

Please help.

Start by inspecting the InsertAsync and UpdateAsync entry points described in the report, then reproduce the behavior with the quoted PostgreSQL table and C# Button class. The fix is complete when both operations handle the case-sensitive Id and other property names consistently without changing the database naming convention.
