libpq knows nothing in particular about composite columns.  You'd need
to parse out the data for yourself, per the syntax rules at
http://www.postgresql.org/docs/8.2/static/rowtypes.html#AEN5986

Depending on what you're doing, it might be better to expand the
column at the server side, ie, "SELECT (ccol).* FROM ..."
