The first action you should do is entering into psql mode as
sudo -u postgres psql
Below is a common script can create a database in psql
update pg_database set datallowconn = TRUE where datname = 'template0'; \c template0 update pg_database set datistemplate = FALSE where datname = 'template1'; drop database template1; create database template1 with template = template0 encoding = 'UTF8'; update pg_database set datistemplate = TRUE where datname = 'template1'; \c template1 update pg_database set datallowconn = FALSE where datname = 'template0'; create database mydb with encoding='utf8' template=template0; create user myuser with encrypted password 'mypass'; grant all privileges on database mydb to myuser;
If everything goes fine, you can check your created database by \l command as below:
\l
The result will be like:
mydb | postgres | UTF8 | en_US.UTF-8 | C | =Tc/postgres +
| | | | | postgres=CTc/postgres +
| | | | | myuser=CTc/postgres
postgres | postgres | SQL_ASCII | en_US.UTF-8 | C |
template0 | postgres | SQL_ASCII | en_US.UTF-8 | C | =c/postgres +
| | | | | postgres=CTc/postgres
template1 | postgres | UTF8 | en_US.UTF-8 | C |
You can also do above directly by adding -c parameter:
sudo -u postgres psql -c "CREATE USER your_user_id with password 'your_password' superuser;"
sudo -u postgres psql -c 'create database confluence with owner your_user_id;'
If you want to encode in UTF8, you need to change teamplate0 in UTF8 first
sudo -u postgres psql update pg_database set datallowconn = TRUE where datname = 'template0'; \c template0 update pg_database set datistemplate = FALSE where datname = 'template1'; drop database template1; create database template1 with template = template0 encoding = 'UTF8'; update pg_database set datistemplate = TRUE where datname = 'template1'; \c template1 update pg_database set datallowconn = FALSE where datname = 'template0';
sudo -u postgres psql -c "create database newid with encoding='utf8' template=template0;"
CREATE DATABASE db_name OWNER = role_name TEMPLATE = template ENCODING = encoding LC_COLLATE = collate LC_CTYPE = ctype TABLESPACE = tablespace_name CONNECTION LIMIT = max_concurrent_connection WITH ENCODING='UTF8'
