I went through and revised this patch. I made the documentation statement less categorical. pg_trgm gist/gin indexes might have lower performance of equality operator search than B-tree. So, we can't claim the B-tree index is always not needed. Also, simple comparison operators are <, <=, >, >=, and they are not supported.
Is "simple comparison" here a well-known term of art? If I read the doc as committed (which doesn't include the sentence above), and if I didn't already know what it was saying, I would be left wondering which comparisons those are. Could we just say "inequality operators"?
