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.
