Thanks to all who suggested indexing; I added an index to
the running database, and delete performance immediately
increased by a factor or 10.
The problem now is that when I "vacuum verbose analyze", the
pg_largeobject system table takes *forever* (tens of minutes).
A new postmaster seems to be spawned. The current psql session seems
to disconnect (no more messages), while a "tail -f postmaster.log" shows the
vacuum proceeding to the other tables.
