Amit Kapila 52d26d560e Allow streaming the changes after speculative aborts. 
Until now, we didn't allow to stream the changes in logical replication
till we receive speculative confirm or the next DML change record after
speculative inserts. The reason was that we never use to process
speculative aborts but after commit 4daa140a2f it is possible to process
them so we can allow streaming once we receive speculative abort after
speculative insertion.

We decided to backpatch to 14 where the feature for streaming in progress
transactions have been introduced as this is a minor change and makes that
functionality better.

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/.
