Finally got a tiny little error message:
sterno.infoplease.com:/u/kdebisschop> psql -p 5433 webusers -c "CREATE INDEX zdaily_id ON daily (id)"
pqReadData() -- backend closed the channel unexpectedly.
This probably means the backend terminated abnormally
before or while processing the request.
We have lost the connection to the backend, so further processing is impossible. Terminating.
[2]+ Done psql -p 5433 webusers -c "CREATE INDEX zdaily_date_n ON daily (date,n)"
sterno.infoplease.com:/u/kdebisschop> psql -p 5433 webusers -c "CREATE INDEX zdaily_id ON daily USING hash (id)"
ERROR: cannot open segment 1 of relation zdaily_id
sterno.infoplease.com:/u/kdebisschop>
Still no core dump. Each of these takes an hour or so to croak.
Any ideas would be welcome.
