Hello,
I double posted this (posted once from an unregistered email and assumed it would be junked).
I'm continuing all discussion on the other thread now.

What version is this?
Hm, so the startup process finds the consistent point (which signals
postmaster so that line 23612/3 says "ready to accept read-only conns")
and immediately dies because of the invalid memory alloc error. I
suppose that error must be while trying to process some xlog record, but
without a xlog address it's difficult to say anything. I suppose you
could try to pg_xlogdump WAL starting at the last known good address
3/8811DFF0 but I wouldn't know what to look for.
One strange thing is that xlog replay sets up an error context, so you
would have had a line like "xlog redo HEAP" etc, but there's nothing
here. So maybe the allocation is not exactly in xlog replay, but
something different. We'd need to see a backtrace in order to see what.
Since this occurs in the startup process, probably the easiest way is to
patch the source to turn that error into PANIC, then re-run and examine
the resulting core file.
