Validation bypass for queries generated for PostgreSQL

When using DB for PostgreSQL, I discovered that if a parameter of a query contains null character, there is a pattern in which subsequent strings are lost.

$ rails new postgresql_rails -TB --database=postgresql
$ cd postgresql_rails

$ bundle exec ruby -v
> ruby 2.5.1p57 (2018-03-29 revision 63029) [x86_64-darwin16]
$ bundle exec rails --version
> Rails 5.2.1

$ bundle install
