Hi!
Here is a rebased version of the patch set.
Major changes are:
1. Fix rare replica fault.
Upon page pruning in heap_page_prune, page fragmentation repair is
determined
by
a parameter repairFragmentation. At the same time, on a replica, upon
handling XLOG_HEAP2_PRUNE record type
in heap_xlog_prune, we always call heap_page_prune_execute with
repairFragmentation
parameter equal to true.
This caused page inconsistency and lead to the crash of the replica. Fix
this by adding new flag in
struct xl_heap_prune.
2. Add support for meson build.
3. Add assertion "buffer is locked" in HeapTupleCopyBaseFromPage.
4. Add assertion "buffer is locked exclusive" in heap_page_shift_base.
5. Prevent excessive growth of xmax in heap_prepare_freeze_tuple.
As always, reviews are very welcome!

Best regards,
Maxim Orlov.
