Fixing issue with MSSQL connection (#8040)

Browse Source 
My team recently faced an issue while using MSSQL and passing a schema
name.

We noticed that "SET search_path TO {self.schema}" is being called for
us, which is not a valid ms-sql query, and is specific to postgresql
dialect.

We were able to run it locally after this fix.
