[Bug]: quoted table name for postgrsql db not supporting with dab version 1.5.43-rc

### What happened?

When I used dab for postfresql then it’s not supported and it’s failing to start with this error
42P01: relations “db.”Employee”” does not exist.

as per db is schema and “Employee” is table name.

{
“source”: {
“object”: “db.\”Employee\””,
“type”: “table”
}
