It's in xaggr.sgml, near the discussion of AggCheckCallContext (the end of section 35.10, in current HEAD's section numbering). In general, people writing C functions should not expect that they can scribble on pass-by-ref arguments, so I don't see a need to belabor the point in multiple places. 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
