Hi,
I don't think I've announced that here yet:
Even since pgadmin.org started shipping their own (different) packages outside
of apt.postgresql.org I stopped updating the pgadmin4 packages in the
repository as I see little value in duplicating that work.
If anyone is interested in adopting the apt.pg.o packages, please get in
contact with me. Otherwise I'd tend to remove the packages in a few weeks.
People wishing to use a replacement from inside apt.postgresql.org or Debian
should have a look at OmniDB (package omnidb-server).
