The idea behind the patch is to store all the files making up a PostgreSQL cluster securely on disk in encrypted format (data-at-rest encryption) and then decrypt blocks as they are read from disk. This only requires that the database is initialized with encryption in mind and that the ke...
修改一个数据库。 ALTER DATABASE name SET parameter { TO | = } { value | DEFAULT } ALTER DATABASE name RESET parameter ALTER DATABASE name RENAME TO new_name ALTER DATABASE name OWNER TO new_owner ALTER DEFAULT PRIVILEGES 定义默认的访问权限。 ALTER DEFAULT PRIVILEGES [ FOR { ROLE | USER...
对角色授予数据库的操作权限: GRANT { { CREATE | CONNECT | TEMPORARY | TEMP } [,...] | ALL [ PRIVILEGES ] } ON DATABASE databasename [, ...] TO { rolename | GROUP groupname | PUBLIC } [, ...] [ WITH GRANT OPTION ] 对角色授予函数的操作权限: GRANT { EXECUTE | ALL [ PRIVIL...
TYPE DATABASE USER ADDRESS METHOD 认证类型(pg_hba.conf - TYPE) local 本地unix socket, host, hostssl, hostnossl ; (host支持hostssl和hostnossl两种模式), ssl表示网络传输的数据使用加密方式传输, 包括认证过程也加密. 认证方法(pg_hba.conf - METHOD) 逐条匹配, 如果匹配到了则不需要往下匹配了. ...
而且对public权限的继承完全不受NOINHERIT的控制,一旦创建了一个拥有login权限的角色,它会立即继承拥有上述权限,此时如果想通过revoke(比如revoke connect on database)来回收的话不会成功,因为这是通过组-组成员来继承的,这种继承权限无法通过单纯的对角色成员revoke掉,只能对组进行revoke,通过继承来实现回收。

I have oracle database to move on to new postgresql server. Some tables are having field sesitive and those are all encryted through DBMS_OBFUSCATION_TOOLKIT.DESENCRYPT/DESDECRYPT. The problem is here. The size of postgresql's encrypted data size(bytea type) should be the same with oracle...
