no, it was that i'd been iterating through a series of
drop table xyz;
create table xyz ( ... );
drop function pdq ( xyz );
create function pdq ( xyz ) returns .... ;
when it reached the "drop function" it was referenceing an old
instance (oid) of the xyz table. then a new function was created
that referred to the new table (oid). i found six such functions
referring to nonexistent tables.
apparently postgresql does cascading correctly on rules, indexes,
and triggers when deleting tables that they depend on. but a function
argument that's defined in terms of a table -- apparently that slipped
through the cracks!
i.e.
create table eg( id int4 );
create index ed_id_idx on eg ( id );
create function go( eg ) .... ;
drop table eg; -- this also drops the index, but not the function
so, instead, now i
drop function pdq ( xyz );
drop table xyz;
create table xyz ( ... );
create function pdq ( xyz ) returns .... ;
dropping the function first, works like a charm.
