Hello!
I'm trying to:
DROP SCHEMA "_old_permissions";
And I get this error:
ERROR: cannot drop schema _old_permissions because other objects depend on
it
DETAIL: function 17059 depends on schema _old_permissions
function 17060 depends on schema _old_permissions
HINT: Use DROP . CASCADE to drop the dependant objects too.
So, naturally I:
DROP SCHEMA "_old_permissions" CASCADE;
Which produces:
NOTICE: drop cascades to 2 other objects
DETAIL: drop cascades to function 17059
drop cascades to function 17060
[Err] ERROR: cache lookup failed for function 17060
What is this trying to tell me?

Apparently you've got some dangling references in pg_depend, ie those
functions were dropped already but the pg_depend entries for them were
not cleaned up.
We've heard similar reports before (usually about temp tables not
functions, IIRC) but never been able to reproduce them or identify a
cause. What PG version is this? Have you done anything funny to that
schema or its contents, or had any crashes around the time of
manipulating either?
As far as cleaning up goes, the thing to do would be to manually delete
the relevant pg_depend entries --- for this one, an entry with objid =
17060 is probably what you're looking for. But it would be good to try
to figure out how you got into this state first.

i had that problem when renaming schema which had already objects inside.
functions inside that schema had references to objects inside that schema.
some functions still had reference to old schema name.
so i renamed it again to drop those objects.
It was 8.3.13 or prior version @ 32bit debian linux .

Worked like a charm, thanks Tom and Viktor.
I’m using version 8.4.5 64bit CentOs Linux
I renamed the schema from permissions to _old_permissions and I believe this caused the error.

Uh, no, certainly not. pg_depend only cares about the objects' OIDs,
not their names. Testing in 8.3, it works fine:
regression=# create schema old_permissions;
CREATE SCHEMA
regression=# create function old_permissions.foo() returns int as
regression-# 'select 2+2' language sql;
CREATE FUNCTION
regression=# create function old_permissions.foo2(int) returns int as
'begin return $1 + 1; end' language plpgsql;
CREATE FUNCTION
regression=# alter schema old_permissions rename to "_old_permissions";
ALTER SCHEMA
regression=# DROP SCHEMA "_old_permissions" ;
NOTICE: function _old_permissions.foo2(integer) depends on schema _old_permissions
NOTICE: function _old_permissions.foo() depends on schema _old_permissions
ERROR: cannot drop schema _old_permissions because other objects depend on it
HINT: Use DROP ... CASCADE to drop the dependent objects too.
regression=# DROP SCHEMA "_old_permissions" CASCADE;
NOTICE: drop cascades to function _old_permissions.foo2(integer)
NOTICE: drop cascades to function _old_permissions.foo()
DROP SCHEMA
regression=#
As I said, we've never seen a reproducible example.
