Hi.

I just noticed that initdb -S ("Safely write all database files to disk
and exit") does (only) the following in perform_fsync:

    pre_sync_fname(pdir, true);
    walkdir(pg_data, pre_sync_fname);

    fsync_fname(pdir, true);
    walkdir(pg_data, fsync_fname);

walkdir() reads the directory and calls itself recursively for S_ISDIR
entries, or calls the function for S_ISREG entries… which means it
doesn't follow links.

Which means it doesn't fsync the contents of tablespaces.
