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.
This sees the addition of a dateOutFormat parameter to ValueInfo::normalize(), as well as a general simplification of how parameter binding works.
Some value type-casting results are slightly different, but this simply makes SQL statement objects consistent with the rest of the system.
