Re: PITR Dead horse? - Mailing list pgsql-hackers

Totally agree. Robustness and rock-solidness are the only
things missing for PostgreSQL to become the killer of certain
commercial enterprise databases out there. And the only thing 
that is missing in this respect is PITR. PITR should be there
INGRES had it in '84 and some people as why PostgreSQL does 
not have it.

I am well versed in the internals of "PITR" features of a certain
leading enterprise-class database out there. And would like to
contribute (write code) to this effort  as much as I can.

Best regards,
Nicolai Tufar
