It's worth pointing out here that catversion was only intended to be
useful within a development cycle, ie, to prevent developers from
wasting time chasing pseudo-bugs that were really due to mismatch of
their newly compiled backend executable with not-so-new system catalog
contents.  We never intended any code to depend on its specific value,
else we'd have used a definition with more mnemonic content than a
date-stamp.
