Teodor Sigaev ff4943042f Fix datatype for number of heap tuples during last cleanup 
It appears that new fields introduced in 857f9c36 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 for
both former fields is of double type.  So, make both those fields in
BTMetaPageData and xl_btree_metadata use float8 type in order to match the
precision of the source.  That shouldn't be double type, because we always
use types with explicit width in WAL.

Patch introduces incompatibility of on-disk format since 857f9c36 commit, but
that versions never was released, so just bump catalog version to avoid
possible confusion.

PostgreSQL Database Management System
=====================================

This directory contains the source code distribution of the PostgreSQL
database management system.

PostgreSQL is an advanced object-relational database management system
that supports an extended subset of the SQL standard, including
transactions, foreign keys, subqueries, triggers, user-defined types
and functions.  This distribution also contains C language bindings.

PostgreSQL has many language interfaces, many of which are listed here:

	https://www.postgresql.org/download

See the file INSTALL for instructions on how to build and install
PostgreSQL.  That file also lists supported operating systems and
hardware platforms and contains information regarding any other
software packages that are required to build or run the PostgreSQL
system.  Copyright and license information can be found in the
file COPYRIGHT.  A comprehensive documentation set is included in this
distribution; it can be read as described in the installation
instructions.

The latest version of this software may be obtained at
https://www.postgresql.org/download/.  For more information look at our
web site located at https://www.postgresql.org/.
