Re: advice on extensions needed

Thanks for the quick responses.  They are very helpful.
  elog(ERROR) is the correct equivalent.  Looks like someone fixed that  already; I can't find elog WARN anywhere in
thecurrent docs, except for
 
  /home/postgres/pgsql/HISTORY: Change elog(WARN) to elog(ERROR)(Bruce)

I was going by the web page
(http://www.postgresql.org/users-lounge/docs/7.0/programmer/xtypes.htm),
which still by the way mentions WARN.  Perhaps they are out of date.

Cheers,
Brook
