Tomas Vondra 75b1521dae Add decoding of sequences to built-in replication 
This commit adds support for decoding of sequences to the built-in
replication (the infrastructure was added by commit 0da92dc530).

The syntax and behavior mostly mimics handling of tables, i.e. a
publication may be defined as FOR ALL SEQUENCES (replicating all
sequences in a database), FOR ALL SEQUENCES IN SCHEMA (replicating
all sequences in a particular schema) or individual sequences.

To publish sequence modifications, the publication has to include
'sequence' action. The protocol is extended with a new message,
describing sequence increments.

A new system view pg_publication_sequences lists all the sequences
added to a publication, both directly and indirectly. Various psql
commands (\d and \dRp) are improved to also display publications
including a given sequence, or sequences included in a publication.

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.
