Make snprintf.c follow the C99 standard for snprintf's result value.
C99 says that the result should be the number of bytes that would have
been emitted given a large enough buffer, not the number we actually
were able to put in the buffer. It's time to make our substitute
implementation comply w

Clean up assorted misuses of snprintf()'s result value.
Fix a small number of places that were testing the result of snprintf()
but doing so incorrectly. The right test for buffer overrun, per C99,
is "result >= bufsize" not "result > bufsize". Some places were also

Update FSM on WAL replay of page all-visible/frozen
We aren't very strict about keeping FSM up to date on WAL replay,
because per-page freespace values aren't critical in replicas (can't
write to heap in a replica; and if the replica is promoted, the values
would be updated by VACUUM anyway). How

Improve comment in GetNewObjectId().
The previous comment gave the impression that skipping OIDs before
FirstNormalObjectId was merely an optimization to avoid likely collisions.
In fact other parts of the system have been relying on this threshold to
detect system-created objects since commit 8e1
