*/20 * * * * /usr/bin/psql -d  tenant_1011046 -q -t -c "GRANT SELECT ON ALL TABLES IN SCHEMA public TO liujunfan;" 
*/20 * * * * /usr/bin/psql -d  tenant_1011046 -q -t -c "GRANT SELECT ON ALL TABLES IN SCHEMA public TO caoxingquan;"

 2. 增加唯一键约束

test=# alter table tbl_unique add constraint uk_tbl_unique_a_b unique (a,b);
ALTER TABLE
