Instability in the test for pg_walinspect revealed that pg_get_wal_records_info_till_end_of_wal(x) would try to decode all the records with a start LSN earlier than the flush LSN, even though that might include a partial record at the end of the range. In that case, read_local_xlog_page_no_wait() would return NULL when it tried to read past the flush LSN, which would be interpreted as an error by the caller. That caused a test failure only on a BF animal that had been restarted recently, but could be expected to happen in the wild quite easily depending on the alignment of various parameters. Fix by using private data in read_local_xlog_page_no_wait() to signal end-of-wal to the caller, so that it can be properly distinguished from a real error.

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.
