Yah was sort of thinking that.

Though what about this -- isn't this case a bit more common

http://postgis.refractions.net/pipermail/postgis-users/2008-September/021393.html

If you have an index on a function that calls another function where the function being called does not have the namespace specifically prefixed.

In his example he had an index on ST_GeometryType (which calls the older function GeometryType both residing in the public schema)

So here is a more trivial example:

using your original

CREATE OR REPLACE FUNCTION foo(integer)
RETURNS integer AS
'select $1+1'
LANGUAGE 'sql' IMMUTABLE;

CREATE OR REPLACE FUNCTION foo2(integer)
RETURNS integer As
$$SELECT foo($1)$$
LANGUAGE 'sql' IMMUTABLE;

CREATE SCHEMA s1;
create table s1.t1 (f1 int);
create index i1 on s1.t1 (foo2(f1));

Try to back that up and then restore it.

error
pg_restore: [archiver (db)] Error from TOC entry 1769; 0 38023 TABLE DATA t1 pos
tgres
pg_restore: [archiver (db)] COPY failed: ERROR: function foo(integer) does not
exist
LINE 1: SELECT foo($1)
^
HINT: No function matches the given name and argument types. You might need to

dy exists
Command was: CREATE INDEX i1 ON t1 USING btree (public.foo2(f1));

Or do people not do this? I tend to a lot.
