Dear managers,
as usual, I got very helpful answers very fast - Thank you!
I had asked:

Well, my fault was to use the "System Administration" manual only -
Chris Ruhnke pointed me to the "man" page of "disklabel"
which explicitly lists the strings "raw" and "database".
Nonetheless, Dr. Thomas Blinn gave a complete answer:
| "disklabel" is the way to go. Note the variation where you can
| set the usage label for a specific partition. You can even have
| embedded blanks, but some applications may be confused by that
| (if you output the label and feed it to "awk" for instance, the
| blank will look like a field delimiter). Few things care what
| you put in the field, and anything other than "unused" counts as
| "used" for things that worry about that.
I decided not to invent my own labels (for the moment) but to stick
to the man page offerings. So I called
disklabel -s rz.. database
for all those partitions, then checked with the graphic tool - voila!
To be sure, I even did a reboot which showed no problems (to be
expected, given the man page - call me paranoid).
Regards and Thanks,
Joerg Bruehe
