Operating system:   Ubuntu 14.4 LTS
Description:

Vacuuming a really big table (139.000.000 records, 66GB tablespace, one
GIN-INDEX of 135 GB!) is consuming extreemly much memory. Much, much more
then maintenance_work_mem (2GB). at this time about 85 GB of virt mem.

see post "autovacuum worker running amok - and me too" at postgresql-general
or ask me for more data. this form is to small for it.
