A single PostgreSQL server can contain many databases. Let’s explore three different approaches to list databases in PostgreSQL!
command invoke \ --resource-group migrate-postgresql \ --name postgresqlvm \ --command-id RunShellScript \ --scripts " # Install PostgreSQL sudo echo deb http://apt.postgresql.org/pub/repos/apt/ bionic-pgdg main > /etc/apt/sources.list.d/pgdg.list sudo wg...
Note:To create aPostgreSQLdatabase, we will execute the“CREATE DATABASE”command from the psql(SQL Shell). You can execute the same command from pgAdmin's query tool to create a database. How to List the Databases? Open thepsql(SQL Shell) and execute the“\l”command to see the list ...
A database cluster is a collection of databases that are managed by a single server instance. Reference: initdb (PostgreSQL Documentation) You did not specify if this is a test machine or planned for prod, but you probably should use the service command to run the initdb and after that sudo...

psql里面有很多\d命令。尽管大多数命令没有指定具体名称，但社区中的大多数人将其称为“描述”、“显示”或“详细信息”命令。就像一个 CLI，它允许您通过键入“help [command]”之类的内容来获取每个命令的帮助。大多数\d命令将通过在末尾添加+运算符，来提供更多详细信息。我只会在下面展示几个示例，但请随意...
