Pattern matching also includes Full-text search, Trigram and Fuzzysearch

Hi,

The tip states: "If you have pattern matching needs that go beyond this,
consider writing a user-defined function in Perl or Tcl."

But there's a Full-text search, Trigram and Fuzzysearch extensions.
Shouldn't they be listed in the tip?
