It looks like they are all very permissive, though I wonder what the legal effect of a license clause that the software be used for Good and not Evil might be. I guess the question is whether we would slurp one of these into our code base, or whether we would add an analog of --with-libxml and provide only a stub implementation when the library is not present. Any opinions? Does anyone know whether any of these implementations are commonly packaged already? ...Robert -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
