Amit Kapila 7f481b8d38 Improve invalidation handling in pgoutput.c.
Fix the following issues in pgoutput.c:

* rel_sync_cache_relation_cb does the wrong thing when called for a cache
flush (i.e., relid == 0). Instead of invalidating all RelationSyncCache
entries as it should, it does nothing.

* When rel_sync_cache_relation_cb does invalidate an entry, it immediately
zaps the entry->map structure, even though that might still be in use. We
instead just mark the entry as invalid and rebuild it at a later safe
point.

* Similarly, rel_sync_cache_publication_cb is way too eager to reset the
pubactions flags, which would likely lead to failing to transmit changes
that we should transmit. In this case also, we just mark the entry as
invalid and rebuild it at a later safe point.

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/.
