解决办法：



yum -y install e2fsprogs-devel uuid-devel libuuid-devel



./configure --prefix=/usr/local/pgsql --with-uuid=ossp



cd /usr/local/pgsql/contrib/uuid-ossp/

make && make install





postgres=# create extension "uuid-ossp" ;

CREATE EXTENSION



安装扩展成功以后，就可以通过uuid_generate_v4()或uuid_generate_v1()查询 



postgres=# select uuid_generate_v4();

           uuid_generate_v4
