Sorry, I tried to describe the issue as best as I could and included the actual log entries only for completeness, but
wasin too much of a hurry to find the correct translations.

Alas, too late, I got rid of the offending 'postgres' database already by dropping and recreating.

No, not at all. Didn't touch it ever after initdb.

Yes. I run the following every night:
su postgres -c '/opt/pgsql/bin/psql -t -c "select datname from pg_database order by datname;" template1 | xargs -n 1
/opt/pgsql/bin/psql-q -c "vacuum verbose analyze;"'

None.

Paranoia, mostly, I think. I'm using PostgreSQL since long before autovacuum was introduced and always thought that it
couldn'tdo any harm to keep my original vacuum job running once every night, even though autovacuum does a remarkable
job,especially for a couple of busy tables where the nightly vacuum was not quite enough. Plus, having the verbose
outputfrom the log, I get useful info for setting the 'max_fsm_pages'/'max_fsm_relations'-options to sensible values.
Isit a problem to have cron'ed VACUUM-runs in parallel with autovacuum?

Ah, well obviously it wasn't - it's always an extremely pleasant surprise when one is actually in dire need of help and
getsan almost immediate and helpful response.
I wish you all happy Easter!
