Postgres SQL error with COALESCE when using callback

I am using a callback like so:

Column::callback(['name', 'id'], function ($name, $id) {
    return view('livewire-partials.something')->with([
        'name' => $name,
        'id' => $id,
    ]);
}),

This causes an SQL error (with PostgreSQL at least): ERROR: invalid input syntax for integer: ""

When looking at the query:
select CONCAT_WS('|**lwdt**|' ,COALESCE(table.name, ''), COALESCE(table.id, '')) AS "callback_2408452824" from "table"

It seems that COALESCE can't handle different data types well. When casting to text, like so, COALESCE(table.id::text, ''), the query works fine.

Start by tracing how Column::callback builds the PostgreSQL query shown in the issue, especially the COALESCE expressions used for callback columns. Reproduce the failure with PostgreSQL and confirm that the generated query handles the integer id without the invalid input syntax error.
