## AI overview

A personal report from CHAR(11) covering talks on PostgreSQL replication. It discusses the evolution of Skytools from Slony, comparisons with other replication solutions, PostgreSQL core replication and streaming protocol support, read scaling, and failover management.

## Source excerpt

CHAR(11) finished somewhen in the night leading to today, if you consider the social events to be part of it, which I definitely do. This conference has been a very good one, both on the organisation side of things and of course for its content. It began with a perspective about the evolution of replication solutions, by Jan Wieck himself. In some way Skytools is an evolution of Slony, in the sense that it reuses the same concepts, a part of the design, and even share bits of the implementation (like the txid_snapshot datatype that were added in PostgreSQL 8.3). The evolution occured in choosing a subset of the features of Slony and then simplifying the user interface as much as possible. And with Skytools 3.0, those features that were removed but still are useful to solve real-life problems are now available too.
