You've broken something and you haven't got the foggiest idea what :-(
... but "increasing the size of the relcache" definitely isn't the
solution, because it isn't fixed-size.

Why do you think it useful to preload something during InitPostgres,
anyway? Any heavily used table will certainly be present in shared
buffers already, and even more surely present in kernel buffers.
