One scenario: You have 5 PostgreSQL servers connecting to one SAN or NAS
which is your /data directory for a single database. You use your
middleware to distribute requests among the servers; One server gets data
write requests, the other 4 get read-only requests.
However, you want to make sure that if your middleware hiccups you don't
corrupt the database files. For this, setting 4 of the servers to "Read Only
Transactions" would be useful.
