ExecuteReturnLastId within postgres



I used ExecuteReturnLastId as follow sample
var id = dbContext.Insert("app").Column("name", newAppName).ExecuteReturnLastId<Int32>("id");
but the result is null. I tried to debug from the lastest main code and I found that in the
ExecuteQueryHandler.cs I have the follow piece of code
_command.Data.InnerCommand.CommandText = _command.Data.Sql.ToString();
with _command.Data.InnerCommand.CommandText == "select lastval();"
and _command.Data.Sql.ToString() == "insert into app(name) values(:name);"

as result the "select lastval();" not get appended to the sql query after the insert but the insert query simply overwrite the select last sql command text.

Attached a workaround patch, not sure if works in all cases but for me it did the trick.

It's seemd that column id is not primary key,or not be set to auto increment.can you have a check?
