Expose 'random_table_name' as a tweak?

DBItest/R/utils.R

Lines 66 to 69 in f19fb4d

	random_table_name <- function(n = 10) {
	# FIXME: Use parallel-safe sequence of numbers
	paste0("dbit", paste(sample(letters, n, replace = TRUE), collapse = ""))
	}

For us, CREATE TABLE abcdefg is not allowed -- all tables must be qualified as part of a namespace.

We already have tweaks$create_table_as to handle this, but it does not cover all the places where CREATE TABLE statements are attempted, e.g.

DBItest/R/spec-result-fetch.R

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 think having tweaks$random_table_name() instead would be a better/more general solution.

Does that sound right? How does one edit the set of tweaks, exactly?
