Does the relevant supporting index exist on the child table?

Yes all the child tables have foreign keys indexed.

 Again I don't want to divert the main topic(trigger creation) . I will

scans all child partitions (which must be using indexes though) but as the
number of partitions increase the time of drop partitions increases.
