table names seem identical

how I can differentiate these:

oamp=# \z public.c3*
                                   Access privileges
 Schema |         Name          | Type  | Access privileges | Column access privileges
--------+-----------------------+-------+-------------------+--------------------------
 public | c3p0_connection_test  | table |                   |
 public | c3p0_connection_test  | table |                   |
(2 rows)

oamp=# select * from pg_tables where tablename = 'c3p0_connection_test';
 schemaname |      tablename       | tableowner | tablespace | hasindexes | hasrules | hastriggers
------------+----------------------+------------+------------+------------+----------+-------------
 public     | c3p0_connection_test | admin      |            | f          | f        | f
(1 row)

oamp=# select version();
                                                  version
