Tom Lane f3d4019da5 Ensure consistent logical replication of datetime and float8 values. 
In walreceiver, set the publisher's relevant GUCs (datestyle,
intervalstyle, extra_float_digits) to the same values that pg_dump uses,
and for the same reason: we need the output to be read the same way
regardless of the receiver's settings.  Without this, it's possible
for subscribers to misinterpret transmitted values.

Although this is clearly a bug fix, it's not without downsides:
subscribers that are storing values into some other datatype, such as
text, could get different results than before, and perhaps be unhappy
about that.  Given the lack of previous complaints, it seems best
to change this only in HEAD, and to call it out as an incompatible
change in v15.

Japin Li, per report from Sadhuprasad Patro

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/.
