ifthere are random extra files in $PGDATA/base, /global or /pg_tblspc. Unfortunately, macOS has the habit to create
suchfiles quite easily. If I read the outcome correctly, we are back at a blacklist approach, so adding ".DS_Store" may
besomething to consider.

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