CREATE TABLE IF NOT EXISTS jobs ( 
JOB_ID varchar(10) NOT NULL , 
JOB_TITLE varchar(35) NOT NULL, 
MIN_SALARY decimal(6,0), 
MAX_SALARY decimal(6,0) 
CHECK(MAX_SALARY<=25000)
);

Output:

postgres=# CREATE TABLE IF NOT EXISTS jobs (
postgres(# JOB_ID varchar(10) NOT NULL ,
postgres(# JOB_TITLE varchar(35) NOT NULL,
postgres(# MIN_SALARY decimal(6,0),
postgres(# MAX_SALARY decimal(6,0)
postgres(# CHECK(MAX_SALARY<=25000)
postgres(# );
CREATE TABLE

Here is command to see the structure of the created table :

postgres=# \d jobs;
             Table "public.jobs"
   Column   |         Type          | Modifiers
------------+-----------------------+-----------
 job_id     | character varying(10) | not null
 job_title  | character varying(35) | not null
 min_salary | numeric(6,0)          |
 max_salary | numeric(6,0)          |
Check constraints:
    "jobs_max_salary_check" CHECK (max_salary <= 25000::numeric)
