Hi! Say, we have data processed by some user function and we want to keep reference to this function in our data. In this case we have two ways - first - store string output of regprocedure, which is not very convenient, and the second - store its OID, which requires slight modification of pg_upgrade (pg_dump and func/procedure creation function).
I've read previous threads about using regproc, and agree that this is not a very good case anyway, but I haven't found any serious obstacles that forbid modifying pg_upgrade this way. -- Regards, Nikita Malakhov Postgres Professional The Russian Postgres Company https://postgrespro.ru/
