Fall back to type casting from the connection adapter
Unfortunately, a11a8ff had no effect as long as using bind param, and was not tested. This ensures making the intent of a11a8ff, which fall back to type casting from the connection adapter. Fixes #35205. ``` % ARCONN=postgresql bundle exec ruby -w -Itest test/cases/relation/where_test.rb -n test_type_casting_nested_joins Using postgresql Run options: -n test_type_casting_nested_joins --seed 55730 # Running: E Error: ActiveRecord::WhereTest#test_type_casting_nested_joins: ActiveRecord::StatementInvalid: PG::InvalidTextRepresentation: ERROR: invalid input syntax for integer: "2-foo" rails test test/cases/relation/where_test.rb:30 Finished in 0.245778s, 4.0687 runs/s, 0.0000 assertions/s. 1 runs, 0 assertions, 0 failures, 1 errors, 0 skips ```
