The benefit is that joining partitioned tables is faster, which encourages the use of partitioning and therefore a more responsive database. In PostgreSQL 13, partition-wise joins allow you to efficiently join tables even when their partition bounds do not match exactly. Previously PostgreSQL allowed you to efficiently join partitioned tables only if they had matching partitioned boundaries. Partitioning splits a table into multiple tables, and done in a way that is transparent to client applications, making it faster to access the needed data. Partitioning allows you to create a more responsive database by segmenting large data sets using range, list or hash keys. Pg_verifybackup assures you that your backups are indeed good and can restore properly. Pg_verifybackup is a new tool that validates not only the integrity of the files in the backup, but also that the write-ahead log records needed to recover the backup are valid. This manifest is a JSON file containing metadata about the backup: a version number, file list, WAL range, and a checksum. Pg_basebackup – the tool for taking a backup of a running PostgreSQL cluster – now provides a backup manifest.

POSTGRESQL 13 FULL

There’s a nice combination of an improvement and a new tool for creating full physical backups. However, this option provides a proactive tool to help in detecting cases early rather than hitting errors in production.

It also won't provide advice on how to fix them - for this, you should consult an expert. This option won't tell you the reason why you are getting such errors.

Pg_catcheck will now verify that the initial files are available for every relation (table or index). If you suspect that your system catalogs are corrupted, this tool may help you figure out exactly what problems you have and how serious they are. Pg_catcheck is a simple tool developed by EDB for diagnosing system catalog corruption. Most of the time, such errors occur while trying to access a table or index. When your database throws an error like 'could not open file base/XXXXX/XXXX”, you know that something is seriously wrong.

POSTGRESQL 13 PASSWORD

SCRAM with channel binding is a variation of password authentication that is easy to use, but much more secure.

Making security easy to use is crucial because hard-to-use features often lead to no security at all. The new enhancement enables SCRAM to use channel binding, which is a feature that allows mutual authentication over an SSL connection when you are not using certificates. Many different security protocols can be used to encode the password sent by the client, e.g., SCRAM-SHA-256. It’s important for these connections to be secure, otherwise there could be an opportunity to impersonate the server, also called a man-in-middle attack. Libpq is the default set of library functions that client applications use to query the database. Avoid man-in-the-middle attacks for passwords As a result, index-only scans will happen more frequently which is especially useful for IoT applications which continuously stream writes to the database. Second, prior to this release, autovacuum would only trigger vacuum operations on updates and deletes but is now enabled for inserts. Our test results indicate that vacuum can be up to 3 times faster when using multiple parallel workers. There are two vacuum-related improvements: parallel vacuuming of indexes and allowing for index-only scans of append only data.įirst, with parallel vacuum, Postgres can now use multiple processor threads to perform vacuum operations faster. The autovacuum feature cleans up dead hidden rows so you don’t have bloat and is similar to Java’s garbage collector. Vacuum up to 3X fasterįor those that are new to PostgreSQL, vacuuming is part of the multiversion concurrency system and removes dead tuples or rows that are created whenever a record is changed or deleted.

POSTGRESQL 13 UPGRADE

Let’s go through some key highlights and give you reasons to upgrade today. The continuous improvement of important but lesser-known features is a real testament to the power and productivity of an open source project. You’ll find changes that include performance, usability, and security improvements, among others. This year there’s not one headline-grabbing feature, but rather a wide variety of improvements along with updates to previously released features. ( agensgraph-git, postgresql-libs-1c, postgresql-libs-9.5, postgresql-libs-9.4, postgresql-src-beta-libs, postgresql-libs-9.PostgreSQL 13 is here, and as always EDB is proud to be among the many global contributors who made this happen.
