Amit Kapila 8d74fc96db Add a view to show the stats of subscription workers. This commit adds a new system view pg_stat_subscription_workers, that shows information about any errors which occur during the application of logical replication changes as well as during performing initial table synchronization. The subscription statistics entries are removed when the corresponding subscription is removed. It also adds an SQL function pg_stat_reset_subscription_worker() to reset single subscription errors. The contents of this view can be used by an upcoming patch that skips the particular transaction that conflicts with the existing data on the subscriber. This view can be extended in the future to track other xact related statistics like the number of xacts committed/aborted for subscription workers.

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/.
