[1] PostgreSQLMessage.ParseRequest.serialize crashes when trying to use more than 2^15-1 parameters

[MrMage]

This calls through to func Utilities.write<T>(array: [T], closure: (inout ByteBuffer, T) -> ()), which calls write(integer: numericCast(array.count), as: Int16.self). And numericCast traps in Release builds for any values outside the representable range.

An example where this can happen is in Fluent queries with \.id ~~ <array with more than 2^15 elements>.

Suggested solution: throw an error when trying to build a query with this many elements.
