The first action you should do is entering into psql mode as
Code Block |
---|
sudo -u postgres psql |
Below is a common script can create a database in psql
Code Block |
---|
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:
Code Block |
---|
\l
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:
Code Block |
---|
sudo -u postgres psql -c "CREATE USER your_user_id with password 'your_password' superuser;" |
Code Block |
---|
sudo -u postgres psql -c 'create database confluence with owner your_user_idnewid;' |
If you want to encode in UTF8, you need to change teamplate0 in UTF8 first
...
Code Block |
---|
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' |
Once you create user successfully, you can try to check by
Code Block |
---|
psql -h localhost -U <your_username> |
To see the database list
Code Block |
---|
\list |
To see the user list
Code Block |
---|
\du |
