PQexecParams and types

Hello

i've read in the docs to use the proper indexes both types must match in
the where clause, to achive this the user can simply put a string into the
side of the equation mark and pgsql will convert it automaticly. my
question is, when I'm using PQexecParams, should I give all the values as
a string, and it will be converted, or I have to figure out the type of
the given field somehow? i'm writing an interface for my php extension(i'm
not statisfied by the boundled), so i cannot figure out the type of the
fields in most cases. what should be done for the best performance in this
situation?

Bye,
