我已经使用“sudo yum install postgresql-server”来安装 postgresql，现在所有二进制文件（如 pg_basebackup、pg_dumpall、pg_restore 等）都位于“/usr/bin”中，而不位于单独的目录，例如在 /usr/local/pgsql/bin' 中，所以当我想要 pg_upgrade 时，或者如果我想寻址我的 puppet 模块中的二进制文件时，我不知道如何寻址二进制目录。
我对 Linux 有点陌生，所以如果这个问题看起来很愚蠢，我很抱歉:)
如果您使用类似 RHEL 的 Linux，您可以找到您正在使用的 *.rpm 并检查软件包。
[root@localhost ~]# rpm -qa|grep postgresql
postgresql15-15.4-1PGDG.rhel7.x86_64 (Use that one!)
postgresql15-devel-15.4-1PGDG.rhel7.x86_64
postgresql15-contrib-15.4-1PGDG.rhel7.x86_64
postgresql15-libs-15.4-1PGDG.rhel7.x86_64
postgresql15-odbc-13.02.0000-1PGDG.rhel7.x86_64
postgresql15-server-15.4-1PGDG.rhel7.x86_64
然后在“检查”中，您将找到 PostgreSQL 二进制文件所在的脚本。
[root@localhost ~]# rpm -q --scripts postgresql15-15.4-1PGDG.rhel7.x86_64
