ok thx for that!

well php null should just be converted to an unquoted sql NULL
in general explicit types should overwrite PDO defaults (see lob issue)
furthermore i agree that in the absence of an explicit type PDO should  
default to the php type. so an integer is bound as an integer, a  
string as a string, and a stream ressource as a lob. obviously a  
numeric string would still be bound as a string.

obviously we need to worry about BC eventually, but i think for now we  
should focus on finding out how we want PDO the behave and later on we  
can think about how/if to handle BC
