If you want fine grained replication, it means you won't be able to use log shipping and streaming replication. If you don't want trigger based replication, you won't have many options still available. pgPool comes to mind but, AFAIK, it isn't fine grained (and, to be honest, I would say it isn't really replication). So, nope, sorry. BTW, what's the issue with trigger-based replication? it really helps a lot in many cases. -- Guillaume http://www.postgresql.fr http://dalibo.com -- Sent via pgsql-general mailing list (pgsql-general@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general

I'm not sure what you want, because pgreplay is certainly not a replication tool, unless replication means something quite different to you than it does to me. Can you be more specific?

Totally agree, for us, a heavily modified version of (what initially was) DBmirror has made the job more than well. Also, our replication is the most fine-grained situation i can think of. (even rows being lazily replicated based on the FK dependency graph, and many other nice tricks) - Achilleas Mantzios IT DEPT -- Sent via pgsql-general mailing list (pgsql-general@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general

Re: [GENERAL] Fine-grained replication?
I should have been more specific about why I'm interested in this. The idea is not so much the replication but being able to use the replication information to make business decisions based on what is observed happening to the data, or being able to selectively repair data if there are problems. XReader certainly shows a lot of promise, but it's not quite here yet. Specific answers to respondents below...

Can you be more specific? Yes, as explained above. So pgreplay in this context would be more likely to be used to repair something.

The worry with trigger-based replication is that it could become a performance bottleneck for heavy loads. We tried out Slony just to see how it worked and it did its job just fine for what we did with it.
