Tom Lane 54100f5c60 Add an enforcement mechanism for global object names in regression tests. 
In commit 18555b132 we tentatively established a rule that regression
tests should use names containing "regression" for databases, and names
starting with "regress_" for all other globally-visible object names, so
as to circumscribe the side-effects that "make installcheck" could have
on an existing installation.

This commit adds a simple enforcement mechanism for that rule: if the code
is compiled with ENFORCE_REGRESSION_TEST_NAME_RESTRICTIONS defined, it
will emit a warning (not an error) whenever a database, role, tablespace,
subscription, or replication origin name is created that doesn't obey the
rule.  Running one or more buildfarm members with that symbol defined
should be enough to catch new violations, at least in the regular
regression tests.  Most TAP tests wouldn't notice such warnings, but
that's actually fine because TAP tests don't execute against an existing
server anyway.

Since it's already the case that running src/test/modules/ tests in
installcheck mode is deprecated, we can use that as a home for tests
that seem unsafe to run against an existing server, such as tests that
might have side-effects on existing roles.  Document that (though this
commit doesn't in itself make it any less safe than before).

Update regress.sgml to define these restrictions more clearly, and
to clean up assorted lack-of-up-to-date-ness in its descriptions of
the available regression tests.

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/.
