This adds seven methods to the output plugin API, adding support for streaming changes of large in-progress transactions. * stream_start * stream_stop * stream_abort * stream_commit * stream_change * stream_message * stream_truncate Most of this is a simple extension of the existing methods, with the semantic difference that the transaction (or subtransaction) is incomplete and may be aborted later (which is something the regular API does not really need to deal with). This also extends the 'test_decoding' plugin, implementing these new stream methods. The stream_start/start_stop are used to demarcate a chunk of changes streamed for a particular toplevel transaction. This commit simply adds these new APIs and the upcoming patch to "allow the streaming mode in ReorderBuffer" will use these APIs.

The PostgreSQL contrib tree --------------------------- This subtree contains porting tools, analysis utilities, and plug-in features that are not part of the core PostgreSQL system, mainly because they address a limited audience or are too experimental to be part of the main source tree. This does not preclude their usefulness. User documentation for each module appears in the main SGML documentation. When building from the source distribution, these modules are not built automatically, unless you build the "world" target. You can also build and install them all by running "make all" and "make install" in this directory; or to build and install just one selected module, do the same in that module's subdirectory. Some directories supply new user-defined functions, operators, or types. To make use of one of these modules, after you have installed the code you need to register the new SQL objects in the database system by executing a CREATE EXTENSION command. In a fresh database, you can simply do CREATE EXTENSION module_name; See the PostgreSQL documentation for more information about this procedure.
