Thanks for the rebase.
Attach the V74 patch set which did the following changes:

v74-0000
-----
This patch is borrowed from[1] to fix the cfbot failure[2].

The reason of the cfbot failure is that:
When rel_sync_cache_relation_cb does invalidate an entry, it immediately
free the cached stuff(including the slot), even though that might still be
in use. For the failed testcase, It received invalid message in
logicalrep_write_tuple when invoking "SearchSysCache1(TYPEOID," and free
the slot memory. So, it used the freed slot values to send which could
cause the unexpected result.

And this pending patch[1] fix this problem by move the memory free code
from rel_sync_cache_relation_cb to get_rel_sync_entry. So, before this
patch is committed, attach it here to make the cfbot happy.
