It would be nice to get support for the Postgres full text search function
`ts_headline`. See https://www.postgresql.org/docs/current/textsearch-
controls.html#TEXTSEARCH-HEADLINE

`SearchHeadline` would also accept an optional `options` argument which
is a where configuration options like `StartSel` and `StopSel` can be
specified.

My proposed implementation work look like this:

{{{#!python
>>> from django.contrib.postgres.search import SearchHeadline, SearchQuery
>>> query = SearchQuery('brave sir robin')
>>> first_line = Line.objects.annotate(
... headline=SearchHeadline('dialogue', query, options={
... 'StartSel': '<b>',
... 'StopSel': '</b>'
... })
... ).first()
>>> print(first_line.headline)
'<b>Robin</b>. He was not at all afraid to be killed in nasty ways.
<b>Brave</b>, <b>brave</b>, <b>brave</b>, <b>brave</b> <b>Sir</b>
<b>Robin</b>'
}}}

I have this implementation ready if this would be accepted:
