For this, there is obviously a requirement that the slave be able to connect to the database on the master. This is not allowed by our security set-up (that's the whole reason for having the replica database). > > I need to somehow push the changes from the master out to the slave. The database is not very complex or large (two main tables with < 100,000 rows) and new rows will be added only every few minutes. A minute or so lag on the copy database is acceptable. I have similar requirements, so I have the master initiate an SSH reverse tunnel to the replica, where pg connects to the local port that is the remote end of that tunnel. -- Scott Ribe scott_ribe@xxxxxxxxxxxxxxxx http://www.elevated-dev.com/ (303) 722-0567 voice -- Sent via pgsql-admin mailing list (pgsql-admin@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-admin
