Can you show us your SQL? The message is clear: you create a new table
with a foreign key to an other table that doesn't exist. An example:
-- first, i create a table with a primary key
test=# create table t1 (id int primary key, foo text);
NOTICE: CREATE TABLE / PRIMARY KEY will create implicit index "t1_pkey" for table "t1"
CREATE TABLE
-- now i create a new table with a foreign key constraint to the first
-- table
test=# create table t2 (id int references t1(id));
CREATE TABLE
--
-- and now i make a mistake
--
test=# create table t3 (id int references t1(id_));
ERROR: column "id_" referenced in foreign key constraint does not exist
