BTW, in case anyone is doubting it, I did a little bit of "perf" tracing
and confirmed Andres' comment here: more than 50% of the runtime of the
bootstrap phase is eaten by the pg_proc seqscans performed by regprocin.
There's nothing else amounting to more than a few percent, so basically
nothing else in bootstrap is worth optimizing before we fix that.
