PDO does not adequately inform PostgreSQL of a parameter's type, so type casts are required. Rather than adding these to each query manually, the queries are instead processed to add type hints automatically. Unfortunately the queries are processed rather naively; question-mark characters in string constants, identifiers, regex patterns, or geometry operators will break things spectacularly.
