in the same directory there is a directory db with 1 file init.sql:
CREATE TABLE accounts (
user_id serial PRIMARY KEY,
username VARCHAR ( 50 ) UNIQUE NOT NULL,
password VARCHAR ( 50 ) NOT NULL,
email VARCHAR ( 255 ) UNIQUE NOT NULL,
created_on TIMESTAMP NOT NULL,
last_login TIMESTAMP
);
insert into accounts(username,password,email,created_on) values ('a','aaa','assdfdas',now())
when I run docker-compose up (if the db is empty) the init.sql file is executed but the database in which it is executed is root and not postgres, How can I change it?

You can use the psql command \connect <db-name> inside your init.sql file in order to connect to the correct database (given that the database already exists).
In your case, the init.sql file would look something like:
\connect postgres <-- connects to the 'postgres' database
CREATE TABLE accounts (
user_id serial PRIMARY KEY,
username VARCHAR ( 50 ) UNIQUE NOT NULL,
password VARCHAR ( 50 ) NOT NULL,
email VARCHAR ( 255 ) UNIQUE NOT NULL,
created_on TIMESTAMP NOT NULL,
last_login TIMESTAMP
);

I am successfully initializg postresql with logs:
When I am running
docker exec -ti bash, then
su quartz
and my result is:
root#3fac28fb199d:/# su quartz
su: user quartz does not exist.
However, I have tried with postgres -> su postgres
I can successfully go in but after that when I run psql it gives me this error
postgres#3fac28fb199d:/$ psql
psql: error: could not connect to server: FATAL: role "postgres" does not exist
Seems like my db and users are not created at all. What could be the problem?
In the docker bash container I need to use
psql dbname username so in my case it worked and my tables were created.
psql quartz quartz
I'm trying to setup a postgres container with ansible, but the database isn't created completely. Via docker logs, it shows that the script has been executed entirely, but the result in always an empty database.

Note: this is only a part of a script that creates all tables and adds sample data.
What's the reason why database5 is not being filled with the tables and data?
I have a database that is about Heroku. A field is automatically filled with the date. I try to use current_timestamp, but it does not seem to work.
Here is the schema of the database.
drop table if exists users;
create table users (
id int GENERATED BY DEFAULT AS IDENTITY PRIMARY KEY,
name varchar,
email varchar,
username varchar,
password varchar,
register_date CURRENT_TIMESTAMP() not null
);
Here is the query:
cur.execute("INSERT INTO users(name, email, username, password) VALUES(%s, %s, %s, %s)", (name, email, username, password))
And here is the error:
ERROR: syntax error at or near "CURRENT_TIMESTAMP"
LINE 7: register_date CURRENT_TIMESTAMP() not null
postgresql doesn't recognize CURRENT_TIMESTAMP() that's why you have to use CURRENT_TIMESTAMP (without parentheses). Next create table query must work for you:
create table users (
id int GENERATED BY DEFAULT AS IDENTITY PRIMARY KEY,
name varchar,
email varchar,
username varchar,
password varchar,
register_date timestamp default CURRENT_TIMESTAMP not null
);
To check that it works just run next query from postgres REPL:
insert into users(name, email, username, password)
values('n', 'e#e.com', 'un', 'pwd');
To add a column with default current timestamp you could use TIMESTAMP type with default value as NOW()
create table users (
id int GENERATED BY DEFAULT AS IDENTITY PRIMARY KEY,
name varchar,
email varchar,
username varchar,
password varchar,
register_date TIMESTAMP DEFAULT NOW()
);
Sample data
INSERT INTO users(name, email, username, password)
VALUES('Foo', 'foo#bar.com', 'bar', 'foobar')
