Amit Kapila 3abe9dc188 Avoid invalidating all RelationSyncCache entries on publication rename. 
On Publication rename, we need to only invalidate the RelationSyncCache
entries corresponding to relations that are part of the publication being
renamed.

As part of this patch, we introduce a new invalidation message to
invalidate the cache maintained by the logical decoding output plugin. We
can't use existing relcache invalidation for this purpose, as that would
unnecessarily cause relcache invalidations in other backends.

This will improve performance by building fewer relation cache entries
during logical replication.

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.
