I have two Postgres databases (7.4 and 8.24) within the same network on
LINUX platforms. Data sources go to both databases.
I'd like to set up one as a near real-time backup to the operational
database. Is it possible to incorporate a trigger upon update (or
insert) on the operational 8.24 database to initiate an update (or
insert) on the backup 7.4 database?
How do most people set up a near real-time backup database? Perhaps
there is something else that acts like a trigger. Any suggestions would
be helpful.
Thanks. Joanne
