通过运行以下命令在 RHEL 6 系统上安装 PostgreSQL 10：
rpm -Uvh --force --nodeps postgresql10-libs-10.0-1PGDG.rhel6.x86_64.rpm
rpm -Uvh --force --nodeps postgresql10-10.0-1PGDG.rhel6.x86_64.rpm
rpm -Uvh --force --nodeps postgresql10-server-10.0-1PGDG.rhel6.x86_64.rpm
rpm -Uvh --force --nodeps postgresql10-contrib-10.0-1PGDG.rhel6.x86_64.rpm
尝试运行 initdb：
cd /usr/pgsql-10/bin
./initdb --locale=C --encoding=UTF-8 -D /opt/postgresql -U postgres
收到以下错误：
/usr/pgsql-10/bin/postgres: error while loading shared libraries: libicui18n.so.42: cannot open shared object file: No such file or directory
no data was returned by command ""/usr/pgsql-10/bin/postgres" -V"
The program "postgres" is needed by initdb but was not found in the
same directory as "/usr/pgsql-10/bin/initdb".
Check your installation.
有人可以帮忙解决这个问题吗？
谢谢。
