Tom Lane 82eed4dba2 Arrange to put TOAST tables belonging to temporary tables into special schemas
named pg_toast_temp_nnn, alongside the pg_temp_nnn schemas used for the temp
tables themselves.  This allows low-level code such as the relcache to
recognize that these tables are indeed temporary, which enables various
optimizations such as not WAL-logging changes and using local rather than
shared buffers for access.  Aside from obvious performance benefits, this
provides a solution to bug #3483, in which other backends unexpectedly held
open file references to temporary tables.  The scheme preserves the property
that TOAST tables are not in any schema that's normally in the search path,
so they don't conflict with user table names.

initdb forced because of changes in system view definitions.

The PostgreSQL contrib tree
---------------------------

This subtree contains porting tools, analysis utilities, and plug-in
features that are not part of the core PostgreSQL system, mainly because
they address a limited audience or are too experimental to be part of
the main source tree.  This does not preclude their usefulness.

Each subdirectory contains a README file with information about the
module.  Most items can be built with `gmake all' and installed with
`gmake install' in the usual fashion, after you have run the `configure'
script in the top-level directory.  Some directories supply new
user-defined functions, operators, or types.  In these cases, after you have
installed the files you need to register the new entities in the database
system by running the commands in the supplied .sql file.  For example,

	$ psql -d dbname -f module.sql

See the PostgreSQL documentation for more information about this
procedure.
