The fact that bit-strings subscript from the left rather than from the right seems pretty odd to me, but it is documented. I wouldn't object to adding a note to somewhere around here, if we can think of a suitable way to word it: http://www.postgresql.org/docs/9.0/static/functions-bitstring.html -- Robert Haas EnterpriseDB: http://www.enterprisedb.com The Enterprise Postgres Company -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
