But the (X)SQLDA does not contain N. It does however contain charset id,
which can be used to obtain "max bytes per char", which can be used in
combination with the buffer size specified in SQLDA to determine N.

Unfortunately, "max bytes per char" requires aquery to a system table,
which fbclient should probably not bother with.
