We (I) missed expanding virtual generated columns in 
get_relation_constraints() in plancat.c.  That way, some opportunities 
for constraint exclusion will be missed if a constraint contains virtual 
generated columns, as can be shown in the attached test case (thanks to 
Richard Guo).  Simple fix attached.
