PostgreSQL Setup

  1. Install PostgreSQL
  2. Login as the default user: `sudo -u postgres psql`
  3. Create a database: `create database <dbname>;`
  4. Create an user account: `create user <username> with encrypted password '<password>';`
  5. Grant database access to the user: `grant all privileges on database <dbname> to <username>;`

                                (Alternative way)
  1. `sudo -u postgres createuser <username>`
  2. `sudo -u postgres createdb <dbname>`
  3. `sudo -u postgres psql`
  4. `alter user <username> with encrypted password '<password>';`
  5. `grant all privileges on database <dbname> to <username> ;`

PostgreSQL commands

1. \? list all the commands
2. \l list databases
3. \conninfo display information about current connection
4. \c [DBNAME] connect to new database, e.g., \c template1
5. \dt list tables of the public schema
6. \dt .* list tables of certain schema, e.g., \dt public.*
7. \dt *.* list tables of all schemas. Then you can run SQL statements, e.g., SELECT * FROM my_table; (Note: a statement must be terminated with semicolon ;)
8. \q quit psql
