Tom Lane 05d8a561ff Clean up handling of XactReadOnly and RecoveryInProgress checks. 
Add some checks that seem logically necessary, in particular let's make
real sure that HS slave sessions cannot create temp tables.  (If they did
they would think that temp tables belonging to the master's session with
the same BackendId were theirs.  We *must* not allow myTempNamespace to
become set in a slave session.)

Change setval() and nextval() so that they are only allowed on temp sequences
in a read-only transaction.  This seems consistent with what we allow for
table modifications in read-only transactions.  Since an HS slave can't have a
temp sequence, this also provides a nicer cure for the setval PANIC reported
by Erik Rijkers.

Make the error messages more uniform, and have them mention the specific
command being complained of.  This seems worth the trifling amount of extra
code, since people are likely to see such messages a lot more than before.

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:

	http://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.  Changes between all PostgreSQL releases are recorded in the
file HISTORY.  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
http://www.postgresql.org/download/.  For more information look at our
web site located at http://www.postgresql.org/.
