Good day.
Chao Li and Sami Imseih, thank you for looking at.
After thinking a bit, I've decided to make sizes of arrays precise:
- OldestMemberMXactId's size remains MaxBackends + max_prepared_xacts.
Instead of changing its size, procno is now adjusted to not include
auxiliary procs.
- OldestVisibleMXactId contains only MaxBackends elemenents now.
It is used only for real backends and not prepared transactions.
All accesses are validated with asserts certainly.
I believe, index transformation in access of OldestMemberMXactId will not
cost much since all this operations are quite rare.
In the loops arrays are accessed directly since limiting loop index is enough.
