Hm.  Salesforce had also run into the issue that the warnings are just
warnings and relatively easy to miss.  What we did there was to change
the elog(WARNING)s near the bottom of load_relcache_init_file to
elog(ERROR), but I'm not sure if I want to recommend doing that in the
community sources.  In commit 5d1ff6bd559ea8df I'd expected that the
WARNINGs would certainly show up in regression test output, and I thought
I'd verified that that was the case --- did that not happen for you?
