In the new test after resetting the stats, we were not waiting for the stats message to be delivered. Also, we need to decode the results for the new test, otherwise, it will show the old stats. In passing, a. Change docs added by commit f5fc2f5b23 as per suggestion by Justin Pryzby. b. Bump the PGSTAT_FILE_FORMAT_ID as commit f5fc2f5b23 changes the file format of stats.

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.
