The patch is using partkeycxt and not rd_partkeycxt. Probably a typo
in the mail. But a wider question, why that context? I guess that
cache context will vanish when that cache entry is thrown away. That's
the reason we have to copy partition key information in
find_partition_scheme() instead of just pointing to it and also use
fmgr_info_copy() there. But if that's the case, buildfarm animal run
with -DCLOBBER_CACHE_ALWAYS should show failure. I am missing
something here.
