This was broken in commit 9c7d06d60680, which inadvertently gave the wrong value to fast_forward in one StartupDecodingContext call. Fix by flipping the value. Add a test for the obvious error, namely trying to initialize a replication slot with an nonexistent output plugin. While at it, move the CreateDecodingContext call earlier, so that any errors are reported before sending the CopyBoth message.

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.
