Andres Freund 1cbc948010 Check interrupts during logical decoding more frequently. 
When reading large amounts of preexisting WAL during logical decoding
using the SQL interface we possibly could fail to check interrupts in
due time. Similarly the same could happen on systems with a very high
WAL volume while creating a new logical replication slot, independent
of the used interface.

Previously these checks where only performed in xlogreader's read_page
callbacks, while waiting for new WAL to be produced. That's not
sufficient though, if there's never a need to wait.  Walsender's send
loop already contains a interrupt check.

Backpatch to 9.4 where the logical decoding feature was introduced.

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:

	http://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
http://www.postgresql.org/download/.  For more information look at our
web site located at http://www.postgresql.org/.
