CREATE DATABASE cannot run inside a transaction block in pgadmin 4

I am triing to run a script in pgAdmin 4, but I get this error:

CREATE DATABASE cannot run inside a transaction block

And this is the script:

CREATE USER ky_auth WITH PASSWORD 'ky_auth';
COMMENT ON ROLE ky_auth IS 'KnowYourself Auth Database User';
CREATE DATABASE ky_auth WITH OWNER = ky_auth;
COMMENT ON DATABASE ky_auth IS 'KnowYourself Auth Database';

CREATE USER ky_pers WITH PASSWORD 'ky_pers';
COMMENT ON ROLE ky_pers IS 'KnowYourself Personal Database User';
CREATE DATABASE ky_pers WITH OWNER = ky_pers;
COMMENT ON DATABASE ky_pers IS 'KnowYourself Personal Database';

CREATE USER ky_oper WITH PASSWORD 'ky_oper';
COMMENT ON ROLE ky_oper IS 'KnowYourself Operational Database User';
CREATE DATABASE ky_oper WITH OWNER = ky_oper;
COMMENT ON DATABASE ky_oper IS 'KnowYourself Operational Database';

CREATE USER knowyourself_tests WITH PASSWORD 'ky_tests' CREATEDB;
COMMENT ON ROLE knowyourself_tests IS 'KnowYourself Integration Tests Database User';

So what I have to change?

Thank you

and if put this above the script:

SET AUTOCOMMIT = ON

Then I get this error:

 unrecognized configuration parameter "autocommit"

if I do this:

CREATE USER ky_auth WITH PASSWORD 'ky_auth';
COMMENT ON ROLE ky_auth IS 'KnowYourself Auth Database User';

then it succeeds. but then If I do this:

CREATE DATABASE ky_auth WITH OWNER = ky_auth;
COMMENT ON DATABASE ky_auth IS 'KnowYourself Auth Database';

I get this error:

ERROR:  CREATE DATABASE cannot run inside a transaction block
