Sounds like that to me too. Are any core dump files showing up in the
database directory (PGDATA/base/DBNAME/core)? If so a stack trace
from the corefile would be informative. Also, make sure you are
collecting a postmaster log --- do NOT start the postmaster with -S,
instead direct its stdout and stderr into a logfile --- and see if
anything interesting is recorded therein. You might want to start the
postmaster with -d2 so that the actual queries are logged too.
