Does the latest PostgreSQL 7.1.2 support database mirroring? I have machine A, B and C, they all have the same database and tables. Machine A is the operational machine, machine B and C are backup. If users do INSERT, UPDATE and DELETE in machine A, I want have the same SQL statements in machine B and C. 1. I can do pg_dump or COPY every hour. 2. I can use PerlDBI or JDBC open multiple connections for each SQL statement. 3. But I prefer if the system auto mirroring the database, then I can do nothing. All I need is set the auto mirroring configure. Please tell me how to do in 3. above. Thank you in advance! ---------------------------(end of broadcast)--------------------------- TIP 1: subscribe and unsubscribe commands go to [EMAIL PROTECTED]
