I just chanced to notice that if someone were to change the value for LOBLKSIZE and recompile, there'd be nothing to stop him from starting that postmaster against an existing database, even though it would completely misinterpret and mangle any data in pg_largeobject.I think there ought to be a guard for that, for exactly the same reasons that we check TOAST_MAX_CHUNK_SIZE: correct interpretation of on-disk data requires that this value match the original database configuration. Obviously it's too late to do anything about this in existing branches, but I propose to add a field to pg_control after we branch off 9.4.
If we did an initdb-requiring change for 9.4 could we piggy-back this onto it?
