    Throw an appropriate error if ALTER COLUMN TYPE finds a dependent trigger. · 1f0b62e8
    Tom Lane authored 
    Actually making this case work, if the column is used in the trigger's
WHEN condition, will take some new code that probably isn't appropriate
to back-patch.  For now, just throw a FEATURE_NOT_SUPPORTED error rather
than allowing control to reach the "unexpected object" case.  Per bug #5688
from Daniel Grace.  Back-patch to 9.0 where the possibility of such a
dependency was introduced.
