Michael Paquier a70e6e4306 doc: Add description of some missing monitoring functions 
This commit adds some documentation about two monitoring functions:
- pg_stat_get_xact_blocks_fetched()
- pg_stat_get_xact_blocks_hit()

The description of these functions has been removed in ddfc2d9, later
simplified by 5f2b089, assuming that all the functions whose
descriptions were removed are used in system views.  Unfortunately, some
of them were are not used in any system views, so they lacked
documentation.

This gap exists in the docs for a long time, so backpatch all the way
down.

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/.
