If dblink was a core module I would say that adding the configure stuff
would be very natural. Since this is contrib stuff I was not that sure
about configure anymore. We will need additional flags for external data
sources in the (hopefully) near future so I think we should add it.
Personally I tend to think about a solution like that. dblink has a
great future and many people simply love it (I cannot think of a
customer who does not like it - it is a killer feature):
- implement the concepts proposed by Joe on this list yesterday (I am
talking about the functions dblink should provide)
- add support to configure
- merge dblink with dblink_ora as soon as the changes are ready
- adapt jdbc_link and merge it with dblink
- implement dblink_db2, dblink_csv, dblink_xml, and maybe some others
- leave it in contrib because this way it will be shipped with the core
distribution and people will use it more frequently
I hope that I will finish the Oracle stuff (named connections, ...)
within the next 3 days.
Regards,
Hans
