An assertion test added in commit049ef33could fail when pg_prewarm() was called on objects without storage, such as partitioned tables. This resulted in the following failure in assert-enabled builds: Failed Assert("RelFileNumberIsValid(rlocator.relNumber)") Note that, in non-assert builds, pg_prewarm() just failed with an error in that case, so there was no ill effect in practice. This commit fixes the issue by having pg_prewarm() raise an error early if the specified object has no storage. This approach is similar to the fix in commit4623d7144for pg_freespacemap. Back-patched to v17, where the issue was introduced.

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.
