Re: Map WAL segment files on PMEM as WAL buffers

Hi Justin,

Here is patchset v8. It will have "make check-world" and Cirrus to
pass. Would you try this one?

The v8 squashes some patches in v7 into related ones, and adds the
following patches:

- v8-0003: Add wal_pmem_map to postgresql.conf.sample. It also helps v8-0011.

- v8-0009: Fix wrong handling of missingContrecPtr for
test/recovery/t/026 to pass. It is the cause of the error. Thanks for
your report.

- v8-0010 and v8-0011: Each of the two is for CI only. v8-0010 adds
--with-libpmem and v8-0011 enables "wal_pmem_map = on". Please note
that, unlike your suggestion, in my patchset PMEM_IS_PMEM_FORCE=1 will
be given as an environment variable in .cirrus.yml and "wal_pmem_map =
on" will be given by initdb.

Regards,
Takashi
