Re: Streaming replication bug in 9.3.2, "WAL contains references to invalid pages"

We had the same issues running 9.2.4:

[2013-10-15 00:23:01 GMT/0/15396] WARNING:  page 8789807 of relation
base/16429/2349631976 is uninitialized

Also on an index. I ended up manually patching the heap files at that
block location to "fix" the problem. It happened again about 2 weeks
after that, then never again. It hit all connected secondaries.
