Dissecting SkyTools

SkyTools is not just a single script but a collection of various tools serving different purposes. Once we have installed SkyTools, it makes sense to inspect these components in more detail:

pgq: A generic queuing interface used to flexibly dispatch and distribute data
londiste: An easy-to-use tool used to replicate individual tables and entire databases on a logical level
walmgr: A toolkit used to manage transaction logging

In this chapter, we will discuss pgq and londiste in detail.
