Hmm ... I'd be against using this in backend/regex/, because I still have hopes of converting that to a standalone library someday (and in any case it needs to stay compatible with Tcl's copy of the code). But otherwise this seems like a reasonable proposal. As for the function name, maybe "qunique()" to go with "qsort()"? I'm not thrilled with "array_unique" because that sounds like it is meant for Postgres' array data types. regards, tom lane -- Sent via pgsql-hackers mailing list (email@example.com) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
