Hmm. So I need to call "|PQparameterStatus" with "|integer_datetimes". 
If I get "TRUE", treat as integer, if I get "FALSE", treat as double. 
What happens if I get NULL? The docs seem to suggest that this is what 
will happen for 7.4 back end, and the FALSE is the default. My 
experience shows, however, that at least 7.4 for Debian Sid should be true.

Not what I have seen from the code, but I will take your word for it.
