Hello, I know that the SQL norm contains some views to describes the tables (and probably some other things) of a database. Does PostgreSQL implement theses views (from which version number) ? I don't find anything in the documentation about that. Thanks in advance ! --------------------------------------- Bruno BAGUETTE - pgsql-ml@baguette.net ---------------------------(end of broadcast)--------------------------- TIP 5: Have you checked our extensive FAQ? http://www.postgresql.org/docs/faqs/FAQ.html
