It would probably help if you supplied some more details, such as how you
"called" them, and how you tested that they are visible etc. Did you create them
 enclosed in double quotes?

eg.
dev=# create table "Foo" (x date);
CREATE TABLE

dev=# select * from Foo;
ERROR:  relation "foo" does not exist

dev=# select * from "Foo";
 x
---
(0 rows)

The best way to get help with these things is to post a "test case" that
shows us exactly how you get this error.  Create table, create function,
insert rows of data, run select, boom ERROR.  If you have one of those,
we can help you quite a bit more than trying to mind read what exactly
the problem might be you're having.

Most likely cause is the schema_path is set wrong or the tables/
functions have been created using quoted names (e.g. "myTable") and
you are calling them without quotes. PostgreSQL folds identifier
names to lower case unless you double quote them.

He could also be calling the functions with the wrong signature (e.g.
create numeric functions and then call them with doubles without using a
cast).

Without more information, trying to help is a shot in the dark.
