我正在尝试连接到外部普及数据库。当我登录到服务器（CentOS 7）并连接到远程服务器时，一切正常，并且可以连接。
我有几个连接和检索数据的perl脚本。当我从命令行运行此程序时，它们毫无问题地连接（无论我以哪个用户身份运行）
但是，当它们通过CRON运行时，出现以下错误：
DBI connect('*REMOVED*','',...) failed: [unixODBC][Driver Manager]Can't open lib '/usr/local/psql/lib64/libodbcci.so' : file not found (SQL-01000)
同样，如果我从命令行运行perl脚本，则不会收到错误消息。如果使用ISQL，我也可以连接到服务器。
如果我尝试以用户身份运行该命令，它也会失败，但是如果我以该用户身份登录，它将运行正常。
/* This works */
su psql
isql -v remote
/* This fails */
sudo -u psql isql -v remote
