While prewarming blocks from a dump file, autoprewarm_database_main() mistakenly ignored tablespace when detecting the beginning of the next relation to prewarm. Because RelFileNumbers are only unique within a tablespace, autoprewarm could miss prewarming blocks from a relation with the same RelFileNumber in a different tablespace. Though this situation is likely rare in practice, it's best to make the code correct. Do so by explicitly checking for the RelFileNumber when detecting a new relation.
