> This seem to be the same problem as already discussed in [1]: Tools like pg_basebackup and pg_checksums can get upset if there are random extra files in $PGDATA/base, /global or /pg_tblspc. Unfortunately, macOS has the habit to create such files quite easily. If I read the outcome correctly, we are back at a blacklist approach, so adding ".DS_Store" may be something to consider.

Yeah. I wonder if we ought to do something more general, and
ignore all files whose names start with ".".
