我的公司有两个开发团队，所以我应该在两台不同的端口上的一台机器上设置两个postgresql实例。我们在测试postgres VM上进行了类似的设置，但版本为9.5 / 9.6。我安装了postgres 10而没有发生任何意外，我正在尝试按照postgres10 docs here上的说明进行操作，但是当我尝试使用initdb或pg_ctl时，我得到以下内容：
postgres@DevPostgres:/usr/local$ whereis pg_ctl
pg_ctl: /usr/share/man/man1/pg_ctl.1.gz
postgres@DevPostgres:/usr/local$ whereis initdb
initdb: /usr/share/man/man1/initdb.1.gz
postgres@DevPostgres:/usr/local$ pg_ctl -D /usr/local/pgsql/data initdb
pg_ctl: command not found
我认为这两个程序将在第一次安装时安装，但是当我按照指向.gz文件的符号链接并解压缩并尝试使用它时，我得到以下内容：
