Percona has a mission to provide the best open source database software, support, and services so our users can innovate freely. The feedback from users was that “backup management is a must ” and “we need something that allows us to manage all of our database backups in one place, not server by server.”

While working as a DBA, we perform many regular tasks, and one of them is upgrading our database systems. There are some techniques to perform a PostgreSQL database upgrade, such as data dump and import, logical replication, or in-site upgrade using pg_upgrade. If all is good, perform the upgrade removing the –check flag.

Among the different components of modern software solutions, the database is one of the most critical. Instead, focus on understanding what the workloads exercise to help us determine how to best use them to aid our performance assessment. We will not concern ourselves with the raw throughput of workload.

Inspired by David’s insights, I embarked on a journey to explore logical replication from a different perspective – within the realm of on-premises server databases.

This can be changed later using the pg_checksums utility, but that will be a painful exercise on a big database. The most common parameter used by the PostgreSQL server (postmaster) will be PGDATA, which sets the parameter data_directory. But changing this is possible only at the server startup. 20150623 (Red Hat 4.8.5-44),

Unfortunately, this topic is more of an art than a science, given that there is really no foolproof algorithm or approach that can tell you exactly where you might hit a bottleneck with server performance. Hardware considerations The first thing we have to consider here is the resources that the underlying host provides to the database.
