[postgres@localhost ~]$ cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys 注意:需要将其他节点的id_rsa.pub文件重命名后拷贝到gtm节点,然后将所有id_rsa.pub文件追加到authorized_keys文件,此处有两个数据节点需要添加进去: cat id_rsa.pub_node1 id_rsa.pub_node2 >> authorized_keys(这样可以实现每...
Ensure that TOAST-able tables use non-TOAST-able primary keys (integers, varchars, etc), and there will only be a modest increase in resource utilization, in addition to increased WAL storage size. Create the Postgres publication. You should include all tables you want to replicate as part ...
In E59 of “5mins of Postgres” we’re talking about UUIDs vs Serials for primary keys. In our last episode, we talked about what happens if you use a regular four byte integer for your primary key and you then run out of space. Today, I want to talk about the scenario where you...

There are two ways to perform a snapshot in chunks: 1) table by table or 2) a large table split into small sets using primary keys or any unique row identifiers. In this approach, the snapshot duration and downtime window is greatly reduced. Good scripting skills requ...

Certificates, private keys, and the revocation list are stored in the per-user file storage area on the server, which is owned by the user account under which the PEM server process is run. This means that administrators of the server might be able to access those files. Use caution before...
rows in sharded tables use a composite key: id, the primary key in the old database; and space_id, the partition key in the current arrangement. Since we had to do a full table scan anyway, we could’ve combined both keys into a single new column, eliminating the need to pass space...
