3.4 Replay Transaction logOnce we have created an initial base backup of our own, we can collect the Xlog created by the database. When the time comes, we can use all these xlog files and perform the recovery process we expect. This works as described in this section.Perform basic recoveryIn PostgreSQL, the entire recovery process has a file management called recover.conf, which resides primarily in the home directory of the underlying backup. It is r

This article mainly introduces some similarities between DB2 database development and PostgreSQL development in actual operations. What's more, I recently used DB2 databases and wrote some differences between them. Not necessarily true. But you can see the difference between the two. 1. Data Definition Language (DDL) and peripheral tools: the difference between DB2 and postgresql is almost 0. The specific

The new database storage engine uses multi-version instead of single-version locking to implement concurrency control without exception. It can be said that multi-version has become a development trend in the future. Although multiple versions are available, the im
