Example for dbFetch() on a dbSendStatement() result?

Lines 87 to 97 in f19fb4d

	fetch_no_return_value = function(con, table_name) {
	#'
	#' Calling `dbFetch()` on a result set from a data manipulation query
	#' created by [dbSendStatement()] can
	#' be fetched and return an empty data frame, with a warning.
	query <- paste0("CREATE TABLE ", table_name, " (a integer)")
	res <- local_result(dbSendStatement(con, query))
	expect_warning(rows <- check_df(dbFetch(res)))
	expect_identical(rows, data.frame())
	},

I'm not sure I understand this, and the example is using dbSendStatement() in a way that differs slightly from the documentation I see (which covers INSERT/UPDATE/DELETE but not CREATE statements).

Do you have an example of a backend that implements this as intended? It's also a bit hard to search for.
