PostgreSQL 17 Beta Released. Here's What You Need to Know

PostgreSQL 17 has been released! With PostgreSQL 17 now available for download and containing many exciting features ranging from performance improvements for SQL queries to updates to the experience of software developers, there are certainly things you wouldn't want to miss out on. This PostgreSQL tutorial will tell you that PostgreSQL 17 has new database security features, a new ability to perform incremental database backups using pg_basebackup, and updates to database monitoring capabilities using the SERIALIZE option together with the EXPLAIN SQL query. This postgres tutorial will also tell you that the PostgreSQL process responsible for reclaiming storage - the PostgreSQL vacuum - has a new data structure responsible for using up to 20 times less memory than usual, and the same process can also use as much memory as you desire if you fiddle with the maintenance_work_mem variable. PostgreSQL 17 also comes with parameters that can control the scalability of transaction, subtransaction and multixact buffers within your object-relational database that is PostgreSQL. PostgreSQL 17 can use the statistics of the SQL query planner and the sort order of WITH SQL queries to optimize these queries. The users of PostgreSQL 17 can split and merge database partitions as well as enjoy new object-relational database management system features with logical database replication using hash indexes for data lookups. Users using the newest version of PostgreSQL Server are also able to use JSON_TABLE features to convert JSON to a PostgreSQL table as well as use JSON-based SQL query functions. Developers using bigger data sets may see up to a 2x performance improvement when exporting large rows using the COPY mechanism. The COPY mechanism also has a new option called ON_ERROR that lets the database copy proceed even when errors are encountered. Every postgresql project also needs PostgreSQL security measures so as far as database security goes, PostgreSQL has a new parameter called sslnegotiation which allows the database to perform direct SSL handshakes. Database backups are also a topic of interest, so in PostgreSQL 17, incremental database backups can now be performed using pg_basebackup as well as combined with the pg_combinebackup utility. This release of PostgreSQL also added a new option to pg_dump, that lets database developers specify a file that contains instructions on what objects to include or exclude from a database backup. Finally, there have been enhancements to the EXPLAIN SQL clause: the SERIALIZE option is now available and the MEMORY option will tell you how much memory the optimizer uses. EXPLAIN now also shows how much time is spent completing I/O reads and writes.
