Fix datatype for number of heap tuples during last cleanup
It appears that new fields introduced in857f9c3 have inconsistent datatypes:BTMetaPageData.btm_last_cleanup_num_heap_tuples is of float4 type,while xl_btree_metadata.last_cleanup_num_heap_tuples is of double type.IndexVacuumInfo.num_heap_tuples, which is a source of values forboth former fields is of double type. So, make both those fields inBTMetaPageData and xl_btree_metadata use float8 type in order to match theprecision of the source. That shouldn't be double type, because we alwaysuse types with explicit width in WAL.Patch introduces incompatibility of on-disk format since857f9c3 commit, butthat versions never was released, so just bump catalog version to avoidpossible confusion.Author: Alexander Korortkov
