We have made pglogical 1.1 packages available for PostgreSQL 9.6beta1 for both rpm and deb based distributions. They are available for install from our standard pglogical package repository.

PostgreSQL 9.6 has a lot of good features; many of the changes are in the SQL planner, aiming to improve performance by carefully selecting the right execution plan. The great thing here is that doing less work makes many queries much, much faster than they were before. First, we are now using Foreign Key data […]
Although in the future most database servers (particularly those handling OLTP-like workloads) will use a flash-based storage, we’re not there yet – flash storage is still considerably more expensive than traditional hard drives, and so many systems use a mix of SSD and HDD drives. That however means we need to decide how to split […]
