CREATE DATABASE blockscout WITH OWNER = postgres;
GRANT ALL PRIVILEGES ON DATABASE blockscout TO postgres;
ALTER USER postgres WITH PASSWORD 'msdkeuii3hInt2asd23ajb09';
or
/password
then enter password 
then ## postgres 10 || 12
sudo vim /etc/postgresql/12/main/pg_hba.conf

Then change this line:
Database administrative login by Unix domain socket
## local      all              postgres                                md5

to:
Database administrative login by Unix domain socket
## local   all             postgres                                peer

Then restart the PostgreSQL service via the 'sudo' command. Then
## psql -U postgres

You will be now entered and will see the PostgreSQL terminal.
Then enter
## \password

And enter the new password for the PostgreSQL default user. 
After successfully changing the password again, go to the pg_hba.conf and revert the change to "md5".
increase max connections on postgresql.conf
