PostgreSQL 15 Released
The PostgreSQL Global Development Group has released version 15 of the open source PostgreSQL database.
PostgreSQL 15 now also includes the SQL standard MERGE command, which “lets you write conditional SQL statements that can include INSERT, UPDATE, and DELETE actions within a single statement.”
According to the announcement, PostgreSQL 15 also includes performance improvements “with noticeable gains for managing workloads in both local and distributed deployments, including improved sorting.” Specifically, PostgreSQL 15 offers improved in-memory and on-disk sorting algorithms, with benchmarks showing increases of 25–400 percent depending on data type.
"The PostgreSQL developer community continues to build features that simplify running high performance data workloads while improving the developer experience," said Jonathan Katz, a PostgreSQL Core Team member.
