Hmmm ... but it sure looks like the values are offset a few fields from
where they belong ... [ meditates awhile... ] Ah, I've sussed it: the
pg_controldata output you showed can be explained exactly by the
assumption that this copy of pg_controldata thinks time_t is 64 bits
wide, where the pg_control file actually has 32-bit-wide time_t fields.
That explains both the ridiculously large dates (quite impossible for
32-bit time_t's) and the offsetting of the following fields.
So the short answer is probably that you're trying to use a 64-bit build
of Postgres against a 32-bit database. You need to get a matching build.
(We really need to stop using time_t in pg_control.h ...)
