That's what the patch I sent previously proposes. And this is 9.5 material, except if we accept that allocate_recordbuf() will fail all the time in case of an OOM (the only code path where we don't need to mandatory fail with OOM for this routine is used only with WAL_DEBUG in xlog.c). Now if we push forward with this patch, and I think we should to maintain compatibility with WAL_DEBUG with previous versions, we'll need to add as well an ERROR when an OOM occurs after XLogReaderAllocate in logical.c, and in pg_rewind's parsexlog.c. -- Michael
