Hi,
While checking some other code I used valgrind and noticed, as I had before,
that XLogInsert showed accesses to unitialized data.
After some searching and playing around I found the source of that:
heap_insert uses a struct xl_heap_insert which in turn has a xl_heaptid member
- which is padded.
COMP_CRC32 will read most of xl_heap_insert (excluding its trailing padding)
and thus generates valgrind warnings...
Questions:
* I don't actually see any real danger in that - correct?
* valgrind is quite usefull for investigating some issues, has a patch
conditionally zeroing or annotating those structs any chances?
