Hi,
I was wondering whether there is a backend function to help finding the
dependencies on a relation.column inside pg_depend. Something like
dependency.c:0255:findAutoDeletableObjects also taking the "refobjsubid"
with the search. This I ask in order to avoid reinventing the wheel :)
Perhaps the "findAutoDeletableObjects" could be used but the function
name is confusing.
Thanks.

TIP 9: In versions below 8.0, the planner will ignore your desire to
choose an index scan if your joining column's datatypes do not
match
