Amit Kapila 40b1491357 Fix incorrect output from pgoutput when using column lists. 
For Updates and Deletes, we were not honoring the columns list for old
tuple values while sending tuple data via pgoutput. This results in
pgoutput emitting more columns than expected.

This is not a problem for built-in logical replication as we simply ignore
additional columns based on the relation information sent previously which
didn't have those columns. However, some other users of pgoutput plugin
may expect the columns as per the column list. Also, sending extra columns
unnecessarily consumes network bandwidth defeating the purpose of the
column list feature.

Regression tests for subscription/logical replication
=====================================================

This directory contains a test suite for subscription/logical replication.

Running the tests
=================

NOTE: You must have given the --enable-tap-tests argument to configure.
Also, to use "make installcheck", you must have built and installed
contrib/hstore in addition to the core code.

Run
    make check
or
    make installcheck
You can use "make installcheck" if you previously did "make install".
In that case, the code in the installation tree is tested.  With
"make check", a temporary installation tree is built from the current
sources and then tested.

Either way, this test initializes, starts, and stops several test Postgres
clusters.

See src/test/perl/README for more info about running these tests.
