I believe the option for a "warm standby" (which sounds like it is what
you need) was made available in 8.2.0.
You'd have to look at the manual though, I haven't had time to
investigate, and I'm not sure whether it's cluster-wide, or
database-specific.

Even with ver 8.1 you can use WAL archive backups (PITR) to implement an incremental backup strategy.

Yes, true, but it's harder with 8.1 as you always have to start from a
base backup and roll WAL logs forward - without a custom script you
cannot "wait" for new WAL logs to arrive and apply them on top of a base
backup.
There is a project in PgFoundry to allow for warm-standby in the 8.0 and
8.1 series, however this is reportedly built-in to 8.2 now.

Yes, I guess that is true with 8.2 but with a few configurations for WAL copying scripts.

Saw the following in documentation that specifies a good flow for doing it --> http://www.postgresql.org/docs/8.2/static/warm-standby.html

I only want one of many databases to be restored to the other server
incrementally.
Is this possible?
If yes, Wht are the steps??

Not sure, but i think WAL based incremental backup is for the whole database
cluster, and not for an specific database, so don't think this is going to
work for you. Is yoor database too large? If not, you could stick to the old
fashioned pg_dump output.

Yes Database size is going to grow very large over time. The situation is
going to be like this that ther is one central server where n nr of
databases are there.
I want one of these databases to be restored to the Other database Server.
What i have found so far implies tht the whole of database server will be
restored not one particular database.

Any light on this ??

pg_dump is a utility for saving a PostgreSQL database into a script or an
archive file. The script files are in plain-text format and contain  the SQL
commands required to reconstruct the database to the state  it       was  in
at  the  time  it  was saved.

"At the time it was saved" What is the meaning of this statement?

When the pg_dump process starts it takes one point and then makes a backup for that specific time even if more updates on the database are happening during the pg_dump process. So when you restore on the other machine it will restore to that specific time when the pg_dump process started.

Correct.  You could replicate its tables to another server with slony
and then use that to make incrementals with PITR.

Maybe a better definition of what you're trying to do from a higher
level would help.

You can use pg_dump while the application(s) that use the database are
active.  pg_dump saves that database at a point in time.  If the
application(s)
continue to modify the database after you use pg_dump, the script/archive
file created by pg_dump will not contain those modifications.

I've been thinking about PITR.  Since we have one production instance
and one test instance of Postgres, in order to perform a PITR
on any particular database would require reloading the entire instance
onto another server, and extracting what I needed.  Clunky, but
do-able.

From my Informix years, I remember a tool that would read your backups,
and extract out whatever you wanted, down to a table level
SQL.  Wouldn't that be ideal....
