I think the question is whether making lots of rows in system catalogs
better is going to have undesirable effects on (a) the size of our
initial on-disk format (i.e. how big an empty database is), (b) the
amount of memory consumed by the syscache and relcaches on workloads
that touch lots of tables/functions/whatever, or (c) CPU consumption
mostly as a result of more cache line accesses for the same operation.
If you can prove those effects are minimal, that'd be a good place to
start.
