Peter Eisentraut fb1a18810f Remove ts_locale.c's lowerstr()
lowerstr() and lowerstr_with_len() in ts_locale.c do the same thing as
str_tolower() that the rest of the system uses, except that the former
don't use the common locale provider framework but instead use the
global libc locale settings.

This patch replaces uses of lowerstr*() with str_tolower(...,
DEFAULT_COLLATION_OID).  For instances that use a libc locale
globally, this will result in exactly the same behavior.  For
instances that use other locale providers, you now get consistent
behavior and are no longer dependent on the libc locale settings (for
this case; there are others).

Most uses of these functions are for processing dictionary and
configuration files.  In those cases, using the default collation
seems appropriate.  At least we don't have a more specific collation
available.  But the code in contrib/pg_trgm should really depend on
the collation of the columns being processed.  This is not done here,
this can be done in a separate patch.

(You can probably construct some edge cases where this change would
create some locale-related upgrade incompatibility, for example if
before you used a combination of ICU and a differently-behaving libc
locale.  We can document this in the release notes, but I don't think
there is anything more we can do about this.)

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.

When building from the source distribution, these modules are not
built automatically, unless you build the "world" target.  You can
also build and install them all by running "make all" and "make
install" in this directory; or to build and install just one selected
module, do the same in that module's subdirectory.

Some directories supply new user-defined functions, operators, or
types.  To make use of one of these modules, after you have installed
the code you need to register the new SQL objects in the database
system by executing a CREATE EXTENSION command.  In a fresh database,
you can simply do

    CREATE EXTENSION module_name;

See the PostgreSQL documentation for more information about this
procedure.
