Oracle to Postgres Migration

I disagree a little with this.  Setting search_path to fix non schema qualified SQL, is not a Best Practice.

You CAN do this and it will work, but it CAN cause trouble if your database has things of the same name. (again a not
BestPractice).
 

My personal opinion on this, is to correct your SQL to include the schema qualified syntax (schema.whatever.)  This way
youare always 100% sure of what you are doing.
 

Just my $0.02

You don't.  Instead, you set "search_path" to include both schemas.
