Patch applied, and other adjustments:

    This patch fixes the error message in get_major_server_version()
    to be "could not parse version file", and uses the full file path
    name, rather than just the data directory path.

    Also, commit 4109bb5de4 added the cause of the failure to the
    "could not open" error message, and improved quoting.  This patch
    backpatches the "could not open" cause to PG 12, where it was
    first widely used, and backpatches the quoting fix in that patch
    to all supported releases.

Because some of the branches are different, I am attaching the applied
multi-version patch.
