This is a back-patch of commit dcb2bda9b7042dbf43f876c94ebf35d951de10e9 of Aug 6 2009, which fixed assorted cases in which plpgsql would fail to cope with composite types that contain any dropped columns. Per discussion, this fix has been out in 9.0 for long enough to make it improbable that it creates any new bugs, so this is a low-risk fix. To make it even lower risk, I did not back-patch the changes in execQual.c, but just accepted the duplication of code between there and tupconvert.c. The added files tupconvert.h and tupconvert.c match their current states in HEAD.
