Antwort Is Postgres 16 faster? Weitere Antworten – Why upgrade to Postgres 15
PostgreSQL 15 contains many new features and enhancements, including: Support for the SQL MERGE command. Selective publication of tables' contents within logical replication publications, through the ability to specify column lists and row filter conditions.Performance. For most workloads, the performance between Postgres and MySQL is comparable with at most 30% variations. On the other hand, regardless of which database you choose, if your query misses an index, it could be 10x ~ 1000x degradation.The PostgreSQL community released version 15 (stable) in October 2022.
Is Postgres version 14 obsolete : The PostgreSQL 14 version is deprecated, but the PostgreSQL package client or server are still installed. You must install the latest versions of the packages (postgresql-15 and postgresql-client-15) and update your clusters with the command pg_upgradecluster (see the man page).
Is Postgres 15 faster
I ran the code run on PostgreSQL v12 in Azure Database for PostgreSQL Flexible Server. Test run on PostgreSQL v15: The same piece of code was run on PostgreSQL v15 in Azure Database for PostgreSQL Flexible Server. We can clearly see that the code snippet on PostgreSQL 15 is 5x faster than PostgreSQL 12.
What’s new in Postgres 16 : In PostgreSQL 16, Parallel Hash Join has been improved and now supports FULL and RIGHT join types. This allows queries that have a FULL OUTER JOIN to be executed in parallel and also allows Right Joins plans to execute in parallel.
Let's do some benchmarks to see how the merge algorithm change affects the performance of PostgreSQL 15. Figure 4 above shows us that PostgreSQL 15 performs much better than PostgreSQL 14 for large sorts with very small values of work_mem . As the work_mem setting is increased, the performance gap decreases.

How fast is postgres 15
In this latest release, PostgreSQL improves on its in-memory and on-disk sorting algorithms, with benchmarks showing speedups of 25% – 400% based on which data types are sorted.PostgreSQL 16 introduces enhancements in replication for seamless data exchange between cluster nodes, improving high availability, scalability, and disaster recovery. Performance improvements include parallel transactions for subscribers and enhanced efficiency with B-tree indexes.Already here we can see that Postgres 14 does much better in the initial data load. As you can see, the throughput of Postgres 14 at 5000 active connections is about 20% higher. At 10,000 active connections the improvement is 50% over Postgres 13, and at lower connection counts you can also see consistent improvements.
