Your assumption is right. No scope is the same as no patent; it won't help to defend PostgreSQL community against rival companies/communities of other DBMSs. Or, I think we can set the scope to what OIN states. Fortunately, anyone can join OIN free of charge.

Are you assuming that developers want to use PG code snippets for non-PostgreSQL or even non-DBMS software? I believe that accepting patented code from companies would be practically more useful for PostgreSQL enhancement and growth. PostgreSQL is now a mature software, and it can be more corporate-friendly like other software under Apache License.
