http://developer.postgresql.org/pgdocs/postgres/dynamic-trace.html#DTRACE-PROBE-POINT-TABLE (... which you now need to update ...) I think your confusion may stem from the fact that the definition of the buffer-read-done probe was actually wrong, AFAICS. The docs say its last 3 args were bools, which was reasonable, but the definition said int for the first of those. Which is what you want now ... regards, tom lane -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
