As usual, PostgreSQL users should carefully test for the incompatibilities before upgrading in production. Improved performance of the replay of 2-phase commits. In 10, partitioning tables is now an attribute of the table: This means that users no longer need to create triggers for routing data; it's all handled by the system. With large datasets this may be time-consuming and will need to be planned carefully. Uses temporary replication slots by default, WAL streaming supported in tar mode (-Ft). Speedups of 2-4x are common with parallel query, and these enhancements should allow those speedups to happen for a wider variety of queries. It will copy the initial data for you and then keep it up to date after that. In my estimation, the features listed above are the most exciting things that users can expect in PostgreSQL 10, which is expected to be released in September. psql now supports \if ... \elseif ... \else ... \endif to make scripting easier, and there are new functions and new roles to allow monitoring tools to run without superuser privileges. Grouping sets now support hash aggregation. Streaming replication is a fast, secure and is a perfect mechanism for high availability/disaster recovery needs. In PostgreSQL 10, partition table feature uses a more sophisticated table distribution method. PostgreSQL 10 adds a new authentication option - SCRAM-SHA-256 - which is superior to MD5 and should be preferred. PostgreSQL 10 came up with declarative partitioning, using two of the three most common partitioning methods: list and range.

This version focuses to enhance of various new features added in PostgreSQL 10. New Integrity Checking Tools. To enhance the working potential of SQL Server 2016, new features ranging from security to querying abilities, Microsoft has incorporated R analytics, cloud integration and other technicalities. pg_basebackup now has --wal-method rather than --xlog-method. Logical replication will allow us to tackle those use-cases. Speedups of 2-4x are common with parallel query, and these enhancements should allow those speedups to happen for a wider variety of queries. initdb and pg_basebackup have a --waldir option rather than --xlogdir. PostgreSQL 10 came up with declarative partitioning, using two of the three most common partitioning methods: list and range. And now, PostgreSQL 11 has introduced the missing piece: hash partitioning.

In PostgreSQL version 10 or less, if you add a new column to a table without specifying a default value then no change is made to the actual values stored. And there's more, but this blog post is too long already. As it works on the whole instance, replicating only part of the primary server is not possible, nor is it possible to write on the secondary. Beta 4 of version 12 was released on 12th Sep 2019. This can be both faster and more convenient than writing an AFTER ROW trigger that is called once per row. Durable Hash Indexes.

In previous versions of PostgreSQL, PostgreSQL supported only table inheritance, which could be used to simulate table partitioning, but it was complicated to set up and the performance characteristics were not that great. The previous serial is implemented by a separate sequence. Parallel Bitmap Heap Scan: One process scans the index and builds a data structure in shared memory indicating all of the heap pages that need to be scanned, and then all cooperating processes can perform the heap scan in parallel.

This simplifies the logic at application level: there is no need for it to know exactly which node is the primary and which ones are the standbys. See also Michael Paquier's blog on this topic. I want to upgrade my Postgres DB without losing the data in the DB. Increased Robustness and Performance for Partitioning However, there are quite a few other significant features as well which could easily have qualified as headline features in a release less jam-packed than this one. Parallel Index Scan and Index-Only Scan: It's now possible for the driving table to be scanned using an index-scan or an index-only scan. However, I think it’s fair to say that this version can be still considered fresh for most users, and surely only a small percentage of users has upgraded. I also need to create any special data types or other database artifacts required for those tables. The new features in PostgreSQL 10 that increase database performance include: Improved Query Parallelism: Basic parallel query was introduced in PostgreSQL 9.6, giving way to expanded capabilities for implementation of greater functionality for real world use cases.

Pub/Sub Notifications. In the latter approach, stealing the hashed password from the database or sniffing it on the wire is equivalent to stealing the password itself, even if you can't compute a preimage.
