CREATE INDEX USING documentation
The following documentation comment has been logged on the website:
Page: https://www.postgresql.org/docs/14/sql-createindex.html
Description:
In the CREATE INDEX
synopsis(https://www.postgresql.org/docs/current/sql-createindex.html), the
USING method parameter is listed, however in the PARAMETERS section USING is
never fully described, nor is there a link to the very help 11.2 Index Types
page (https://www.postgresql.org/docs/14/indexes-types.html).
On a related note, the CREATE INDEX page provides the following blurb:
"Prior releases of PostgreSQL also had an R-tree index method. This method
has been removed because it had no significant advantages over the GiST
method. If USING rtree is specified, CREATE INDEX will interpret it as USING
gist, to simplify conversion of old databases to GiST."
But there is no such blurb on the 11.2 Index Types page.
Thanks,

Well, that is certainly odd. The attached patch adds a description of
the option, and a link to the chapter you suggested.

We think of backward compatibility stuff as operational, meaning it
appears in the command manual page but not necessarily in the main docs.

Backpatched to PG 10. Thanks for the report, and it is very odd this
was undocumented for so long.
