Fixed #28041 -- Added Lexeme expression to contrib.postgres.search.

Browse Source 
This expression automatically escapes its input and allows
fine-grained control over prefix matching and term weighting
via logical combinations.

Thanks Mariusz Felisiak, Adam Zapletal, Paolo Melchiorre,
Jacob Walls, Adam Johnson, and Simon Charette for reviews.

:mod:`django.contrib.postgres`
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
* The new :class:`Lexeme <django.contrib.postgres.search.Lexeme>` expression
for full text search provides fine-grained control over search terms.
``Lexeme`` objects automatically escape their input and support logical
combination operators (``&``, ``|``, ``~``), prefix matching, and term
weighting.
* Model fields, indexes, and constraints from :mod:`django.contrib.postgres`
now include system checks to verify that ``django.contrib.postgres`` is an
installed app.
