Noticed on IRC:

(10:02:31) SAS: Are there known issues compiling Slony-1.2.0 against
PG8.2beta3 ?
(10:03:11) SAS: I can't link dbutils.o 'cause pg_qsort object seems not
to be found

SAS wasn't on when I noticed this; yes, there is something of an issue.

I noticed this the other week, and checked it into CVS on Oct 27th:

http://gborg.postgresql.org/pipermail/slony1-commit/2006-October/001223.html

The relevant change involves adding the following to confoptions.c:

#ifdef qsort
#undef qsort
#endif
