Fujii Masao 3c4d7557e0 Fix assertion failure in pg_prewarm() on objects without storage. 
An assertion test added in commit 049ef33 could 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 commit 4623d7144 for pg_freespacemap.

Back-patched to v17, where the issue was introduced.
