array_agg and libpq(xx)

Hi,

Anyone here passed array to C/c++ code via libpq(xx) ??
I need to pass on an array of strings, some of them might contain coma symbol.
I am wondering, if there's anything already in libpq(xx) that would
chop value into an array of char* , or will it just return a string
and it is up to user to chop it.

thanks.
