下面是一個自 7.2 版本發佈以來進入 PostgreSQL 開發版本分支的 變化．對於完整修改的清單，請參考 CVS 日誌．
+ The last vestiges of support for type names datetime and timespan are gone; use timestamp and interval instead
Rule names are now per-relation, not global; DROP RULE and COMMENT ON RULE syntax changes accordingly
Readline and Zlib are now required by default and must be turned off explicitly if their use is not desired
Define a third class of function volatility to allow indexscans in more cases
Locale support is now built by default; choice of locale is set by initdb and/or at run-time
ALTER TABLE ALTER COLUMN SET/DROP NOT NULL
EXPLAIN 輸出以查詢結果的形式輸出，而不是 NOTICE 資訊
DOMAINs (那些基本類型的約束類型)
函數的存取權限
過程語言的存取權限
CREATE DATABASE 有了 OWNER 選項，這樣超級使用者可以為其它人建立 DB
Kerberos 5 支援現在可以用於 Heimdal
資料庫和使用者宣告的運行時配置變數的會話預設
(ALTER DATABASE ... SET and ALTER USER ... SET)
