Dear mailing-list,

I am currently worried about an error that shows up in our log files since
a few weeks:

2013-11-15 07:13:13 UTC [22668]: [2-1] ERROR: MultiXactId 2683601542 does
no longer exist -- apparent wraparound
2013-11-15 07:13:13 UTC [22668]: [3-1] CONTEXT: automatic vacuum of table
"scoreloop.public.gamer_device_sightings"

It seems that "autovacuum" is active on that table, but it seems to have
restarted today in the morning:

select query_start, query, state, pid from pg_stat_activity where query
LIKE 'autovacuum%' ;

XXX=# select query_start, query, state, pid from pg_stat_activity where
query LIKE 'autovacuum%' ;

query_start | query
| state | pid
