postgresql-17.0-1-windows-x64.exe
It is fully ACID compliant, has full support for foreign keys, joins, views, triggers, and stored procedures (in multiple languages). It includes most SQL:2008 data types, including INTEGER, NUMERIC, BOOLEAN, CHAR, VARCHAR, DATE, INTERVAL, and TIMESTAMP. It also supports storage of binary large objects, including pictures, sounds, or video. It has native programming interfaces for C/C++, Java, .Net, Perl, Python, Ruby, Tcl, ODBC, among others, and exceptional documentation (table sizes can go up to 32 TB).
PostgreSQL 2024 comes with many features aimed to help developers build applications, administrators to protect data integrity and build fault-tolerant environments, and help you manage your data no matter how big or small the dataset. In addition to being free and open-source, the tool is highly extensible. For example, you can define your own data types, build out custom functions, even write code from different programming languages without recompiling your database!
The app tries to conform with the SQL standard where such conformance does not contradict traditional features or could lead to poor architectural decisions. Many of the features required by the SQL standard are supported, though sometimes with slightly differing syntax or function. Further moves towards conformance can be expected over time. As of the version 11 release in October 2018, Postgre SQL 64bit version conforms to at least 160 of the 179 mandatory features for SQL:2011 Core conformance, whereas of this writing, no relational database meets full conformance with this standard.

What's new in this version:
- New memory management system for VACUUM, which reduces memory consumption and can improve overall vacuuming performance
- New SQL/JSON capabilities, including constructors, identity functions, and the JSON_TABLE() function, which converts JSON data into a table representation
- Various query performance improvements, including for sequential reads using streaming I/O, write throughput under high concurrency, and searches over multiple values in a btree index
- New client-side connection option, sslnegotiation=direct, that performs a direct TLS handshake to avoid a round-trip negotiation
- pg_basebackup now supports incremental backup
- COPY adds a new option, ON_ERROR ignore, that allows a copy operation to continue in the event of an error
Logical replication enhancements, including:
- Failover control
- pg_createsubscriber, a utility that creates logical replicas from physical standbys
- pg_upgrade now preserves replication slots on both publishers and subscribers
