Should 6.5.X still be supported? 7.0.X was released in April and 7.1 will come
soon, as Bruce Momjian told me.

I read his mail and also the section about DB links in our Oracle7 SQL Language
Reference Manual. I used a similar feature in my M$-Access applications, but I didn't
use it in Oracle until now. Do you know, if postgreSQL also has such a feature?

I think the usage of DB-links is transparent for DML-queries and concerns only
DDL-queries, because we need a CREATE/DROP DATABASE LINK statement.
As we discussed some time ago, the DDL-queries should be defined in a database DTD,
that Rodrigo wanted to develop, right?
