Still I would prefer a better handling by ecpg. :-)

I do not know a way other than querying the data dictionary. What does the
standard say? Should we return such info?
What do other RDBMS do in this scenario?
Is there a way I can give this info back anyway. Right now I cannot imagine
one since we give back the whole tuple at once. Where shall we store these
per attribute infos?
