re: *work_mem. They are the defaults. In fact, i only changed
checkpoint_segments to 64 because of too frequent checkpointing. All others

re: PostGIS. Yes, the table has 3 geometries. Most of the database is
tables with geometries and some are far larger than that one and most of
the largest will have been loaded before that one.
It's running again after changing the sysctl setting and i'm monitoring
memory. Will keep you posted.
Thanks
