PostgreSQL 9.5 was officially released this morning with several exciting new features.
First up, PostgreSQL 9.5 adds UPSERT, a simplified shorthand for doing an INSERT to the database but on conflict to update the record. This PostgreSQL support also eases in migrating legacy MySQL programs to PostgreSQL.
PostgreSQL 9.5 also brings new big data features including BRIN indexing, faster sorts, CUBE / ROLLUP / GROUPING SETS, foreign data wrappers, and TABLESAMPLE.
SQLite 3.10 has been released today as the latest version of this widely-used SQL database engine library.
