Tom Lane 41e461d36f Improve define_custom_variable's handling of pre-existing settings.
Arrange for any problems with pre-existing settings to be reported as
WARNING not ERROR, so that we don't undesirably abort the loading of the
incoming add-on module.  The bad setting is just discarded, as though it
had never been applied at all.  (This requires a change in the API of
set_config_option.  After some thought I decided the most potentially
useful addition was to allow callers to just pass in a desired elevel.)

Arrange to restore the complete stacked state of the variable, rather than
cheesily reinstalling only the active value.  This ensures that custom GUCs
will behave unsurprisingly even when the module loading operation occurs
within nested subtransactions that have changed the active value.  Since a
module load could occur as a result of, eg, a PL function call, this is not
an unlikely scenario.

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.

User documentation for each module appears in the main SGML documentation.

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.
