* together provide logical decoding, primarily by providing so

* create and consume a changestream with a low amount of code. Builtin
* consumers are the walsender and SQL SRF interface, but it's possible to
* add further ones without changing core code, e.g. to consume changes in
* a bgworker.
*
* The idea is that a consumer provides three callbacks, one to read WAL,
* one to prepare a data write, and a final one for actually writing since
* their implementation depends on the type of consumer. Check
* logicalfunc.c for an example implementations of a fairly simple consumer

* simpler consumers.
