I don't think this is quite as simple as you paint it.  How can you
process pg_type.dat first, when it contains pg_proc references?  Doing
pg_proc first is no better, because it contains pg_type references.

I believe it's soluble, but it's going to take something more like
loading up all the data at once and then doing lookups as we write
out the .bki entries for each catalog.  Fortunately, the volume of
bootstrap data is small enough that that won't be a problem on any
machine capable of running modern Postgres ...
