Robert Haas 32ba2b5160 Use memcmp() rather than strncmp() when shorter string length is known.
It appears that this will be faster for all but the shortest strings;
at least one some platforms, memcmp() can use word-at-a-time comparisons.

Noah Misch, somewhat pared down.

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.
