Upstream fix:
http://developer.postgresql.org/cvsweb.cgi/pgsql/contrib/tsearch2/tsvector.c?r1=1.26&r2=1.26.2.1
This looks fine for an SRU, too. Reproduction recipe:
$ apt-get install postgresql-8.2 postgresql-contrib-8.2
# drop default cluster and create one with locale "C", to work with the
reproducer script
$ sudo pg_dropcluster 8.2 main --stop
$ sudo pg_createcluster 8.2 main --locale C --start
$ run reproducer:
$ sudo -u postgres -i
$ createdb test
$ psql test -f crashme.sql
This will spin the CPU and hang for a while, until it eventually
crashes.
** Changed in: postgresql-8.2 (Ubuntu)
