Create a table for a demo:
CREATE TABLE your_table(
    thekey   integer NOT NULL,  
    ticker   character varying(10) NOT NULL,
    date_val date,
    open_val numeric(10,4) NOT NULL
); 
pg_dump manual, can output the table create psql statement:
pg_dump -U your_user your_database -t your_table --schema-only
Which prints:
-- pre-requisite database and table configuration omitted
CREATE TABLE your_table (
    thekey integer NOT NULL, 
    ticker character varying(10) NOT NULL, 
    date_val date,  
    open_val numeric(10,4) NOT NULL 
); 
-- post-requisite database and table configuration omitted
