That API is already exposed, so not sure why you say this now? This has been in PG since early in 9.2, about 2 years ago. In any case, "flashback database" is one of the most requested features I know of... the ability to dump the database as it appeared in the past *after* that point has passed. I call it by its name as used in Oracle, but many people have taken the trouble to describe that in detail to me, even without knowing a similar feature existed elsewhere. So it will always be important to do SET TRANSACTION SNAPSHOT 'a point in the past' and if we can do that, why not pg_dump also? -- Simon Riggs http://www.2ndQuadrant.com/ PostgreSQL Development, 24x7 Support, Training & Services -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
