Hi,
While WAL summaries feature and some support functions have been added
in version 17, merely listing the contents of the pg_wal/summaries
directory is missing. As discussed in the pg_ls_archive_status()
discussion, it would be convenient to add pg_ls_summariesdir() that
lists the contents of the pg_wal/summaries directory with the pg_monitor
role.
This patch is based on a very recent master and does not include the
catversion bump.
Best,
Yushi
