PostgreSQL for Mac is a strong, open source object-relational database program. It's over 15 decades of active development and an established architecture that has earned it a solid reputation for reliability, data integrity, data integrity, and correctness. PostgreSQL for Mac is your default database on Mac OS X Server instead of variant 10.7. 

It's fully ACID compliant, has complete support for foreign keys, joins, views, triggers, and stored procedures (in numerous languages). It comprises most SQL:2008 information types, including INTEGER, NUMERIC, BOOLEAN, CHAR, VARCHAR, DATE, INTERVAL, and TIMESTAMP. In addition, it supports storage of binary large objects, such as images, sounds, or video. It has native programming interfaces for C/C++, Java, .Net, Perl, Python, Ruby, Tcl, ODBC, amongst others, and unique documentation (table dimensions can move up to 32 TB).
