While we're talking Oracle... :-)
I attended an Oracle sales talk last week. Well, it was labeled "Technical
information", but that's another story.
I'd like to ask if PostgreSQL has some of the features being promoted.
Log miner. A tool that walks the Undo logs an returns statements to update
with old data. Could be useful for recovering specific table data, Data
Mining etc.
In the PostgreSQL world, it couldn't be dificult to do the same with WAL,
or?
Locator. As I recall, it is a GIS app, written into Oracle. Someone may know
more?
Feature index. Interesting feature from Virage. It indexes LOBs, say a
picture or an videostream. Makes it possible to find closest match.
Fine Grain Audit. Some rules based autit mechanism where you can log e.g.
all access to specific data.
Information Life Cycle Management. A built-in way to degrade data
importance. Maybe you want to move old rows onto cheaper disks, compress
them or so.
