I built a standby with 9.4.12 and about a day later the standby crashed
with this:
2018-02-02 16:20:44 EST,0, WARNING: page 1347460 of relation
base/16391/16414 is uninitialized

terminated by signal 6: Aborted

Any hints to where the corruption begins? I don't see any disk i/o
issues. Not sure what to look for in the release notes,
but I'll try to patch asap, but that is difficult to get done politically.
