Forthose curious, the exact escaping performed on the string may vary slightly depending on your database configuration.
For example, if your database's standard_conforming_strings variable is OFF, backslashes are treated as a special character and pg_escape_string() will ensure they are properly escaped. If this variable is ON, backslashes will be treated as ordinary characters, and pg_escape_string() will leave them as-is. In either case, the behavior matches the configuration of the database connection.
