You are entirely mistaken.  That's not only "supported", it's *required*.
Consider binary upgrades, where the SQL objects are transferred as-is
but the receiving installation may have a different (hopefully newer)
version of the .so.  That .so has to cope with the older SQL object
definitions; it doesn't get to assume that the upgrade script has been
run yet.
