The formatting function API can be pretty simple:
text *my_copy_format(text *attrdata, int direction, int nattrs, int attr, oid attrtype, oid relation)
This seems like it could only reasonably be implemented as a C function. I can't really imagine the average user of COPY wanting to write C in preference to, say, an external perl script. What's the real use-case for the feature?
That is why I suggested providing a pre-written/pre-compiled/installed function for CSV (call it CSV?). Advanced users could still write their own as people can write many other things if they know their ways.
