GRANT ALL ON ALL TABLES IN SCHEMA public TO u;
以u身份登录,您现在可以对预先存在的表a执行此操作：
SELECT * FROM a;
但是如果你现在创建表b并执行：
SELECT * FROM b;
你得到：
ERROR: permission denied for relation b sql state: 42501
这可以通过重新执行来解决
GRANT ALL ON ALL TABLES IN SCHEMA public TO u;
但是每次创建表格之后必须记住这样做是个问题.
有没有办法让Postgresql自动将这些全局授权应用于新创建的表？

例如：
alter default privileges in schema public grant all on tables to u; alter default privileges in schema public grant all on sequences to u;
Description
ALTER DEFAULT PRIVILEGESallows you to set the privileges that will
be applied to objects created in the future. (It does not affect
privileges assigned to already-existing objects.) Currently,only the
privileges for tables (including views),sequences,and functions can
be altered.You can change default privileges only for objects that will be
created by yourself or by roles that you are a member of. The
privileges can be set globally (i.e.,for all objects created in the
current database),or just for objects created in specified schemas.
Default privileges that are specified per-schema are added to whatever
the global default privileges are for the particular object type.As explained under
GRANT,the default privileges for any object type
normally grant all grantable permissions to the object owner,and may
grant some privileges toPUBLICas well. However,this behavior can
be changed by altering the global default privileges withALTER DEFAULT PRIVILEGES.
