In patch "Handle equality operator in contrib/pg_trgm" (935f66665), I
see this text:
--> <literal>~</literal> and <literal>~*</literal> queries. Beginning in
--> <productname>PostgreSQL</productname> 14, these indexes also support
equality operator (simple comparison operators are not supported).
Note that those indexes may not be as efficient as regular B-tree indexes
for equality operator.
As far as I know, we don't usually mention what version _added_ a
feature like this. I suggest the PG 14 mention be removed.
