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.
Major enhancements include:
Logical replication using publish/subscribe.
Declarative table partitioning.
Improved query parallelism.
Significant general performance improvements.
Stronger password authentication based on SCRAM-SHA-256.
