well, it seems to move around. once per 'pg_dumpall' attempt,
but not always in the same spot...

turns out you're right again. :)
i'm doing the "build a structure while ramping up the learning
curve" thing, so i create and drop stuff regularly while i get
this humming the way i want it to...
-- this kind of thing
drop table XYZ;
create table XYZ ( ... );
drop function munge( XYZ );
create function munge( XYZ ) returns ... as ... ;
now i've moved my 'drop function' to BEFORE/ABOVE the drop table,
and all is well when i iterate to a new instance of sql code.
when i did as you recommended:

i found several functions with the same name, but different arg
types, because each was referring to a table-def that no longer
existed.
which explains the next thing:

so maybe extra hooks need to be added to be sure that procedures
that depend on tables being dropped, are also dropped at the same
time? just like the 'warning: dropping indexes and rules and
triggers based on this here table you're dropping...' thing?
