No, pginfo, suposse this example
Web server or cluster web server, it's unimportant
|
Postgresql cluster server containing{
...
Real server 1 running postgresql processes
Real server 2 running postgresql processes
....
}
|
File server machine that contains all pg_databases
Notice that the real servers don't have in their hard disk any database,
they could have a link to the hard disk in the File server machine.
The syncronization between postgresql processes that are running on
different machines and using the same database is my question.
Thanks for the answer
