編輯短評
PostgreSQL 是一款強大的開源關聯式資料庫系統,旨在提供可靠且正確的資料儲存解決方案。它支援絕大多數的 SQL 資料型別以及圖片、聲音與影像等二進位資料,並提供多種原生程式設計介面供開發者調用。由於其架構經過嚴格驗證且長期維護,在同類工具中屬於主流首選,是追求穩定性與功能強大的免費資料庫方案。
這套軟體適合需要自行架設網站的中小企業或軟體開發者,尤其在對系統記憶體佔用較敏感的情境下非常實用。相較於部分針對特定功能收費的替代方案,PostgreSQL 提供了極具競爭力的開源選擇。使用者在下載前需留意其主要支援英文語系,且可運行於 Windows、macOS 及 Linux 等多數主流作業系統。
軟體介紹
它可在所有主流作業系統上執行,包括 Linux、UNIX(AIX、BSD、HP-UX、SGI IRIX、macOS、Solaris、Tru64)以及 Windows。PostgreSQL 是一款強大的物件關聯式資料庫管理系統!下載適用於 PC 的 PostgreSQL 離線安裝程式 64 位元版本!
它完全符合 ACID 規範,並完整支援外部鍵、聯結、檢視、觸發器以及預存程序(支援多種語言)。它包含大多數 SQL:2008 資料型別,包括 INTEGER、NUMERIC、BOOLEAN、CHAR、VARCHAR、DATE、INTERVAL 和 TIMESTAMP。
它也支援儲存二進位大型物件,包括圖片、音訊或影片。它具備 C/C++、Java、.Net、Perl、Python、Ruby、Tcl、ODBC 等原生程式設計介面,並提供卓越的文件(資料表大小最高可達 32 TB)。
PostgreSQL 2026 具備許多功能,旨在協助開發人員建置應用程式、協助管理員保護資料完整性並建置容錯環境,同時協助您管理任何規模的資料集。除了免費且開放原始碼之外,這款工具還具有高度擴充性。
例如,您可以定義自己的資料型別、建立自訂函式,甚至使用不同的程式語言撰寫程式碼,而無需重新編譯資料庫!
此應用程式力求在符合 SQL 標準的同時,不與傳統功能牴觸,也不會導致不良的架構決策。
SQL 標準要求的許多功能都已支援,不過有時語法或功能會略有差異。未來可望進一步提升標準符合度。

更新日誌
9.5.4 - Fix possible mis-evaluation of nested CASE-WHEN expressions. A CASE expression appearing within the test value subexpression of another CASE could become confused about whether its own test value was null or not. Also, inlining of a SQL function implementing the equality operator used by a CASE expression could result in passing the wrong test value to functions called within a CASE expression in the SQL function's body. If the test values were of different data types, a crash might result; moreover such situations could be abused to allow disclosure of portions of server memory.
- Fix client programs' handling of special characters in database and role names.
- Fix corner-case misbehaviors for IS NULL/IS NOT NULL applied to nested composite values
- Fix "unrecognized node type" error for INSERT ... ON CONFLICT within a recursive CTE (a WITH item)
- Fix INSERT ... ON CONFLICT to successfully match index expressions or index predicates that are simplified during the planner's expression preprocessing phase
- Correctly handle violations of exclusion constraints that apply to the target table of an INSERT ... ON CONFLICT command, but are not one of the selected arbiter indexes Such a case should raise a normal constraint-violation error, but it got into an infinite loop instead.
- Fix INSERT ... ON CONFLICT to not fail if the target table has a unique index on OID
- Make the inet and cidr data types properly reject IPv6 addresses with too many colon-separated fields
- Prevent crash in close_ps() (the point ## lseg operator) for NaN input coordinates.Make it return NULL instead of crashing.
- Avoid possible crash in pg_get_expr() when inconsistent values are passed to it
- Fix several one-byte buffer over-reads in to_number()
- Do not run the planner on the query contained in CREATE MATERIALIZED VIEW or CREATE TABLE AS when WITH NO DATA is specified
- Avoid unsafe intermediate state during expensive paths through heap_update()
- Fix hint bit update during WAL replay of row locking operations
- Avoid unnecessary "could not serialize access" errors when acquiring FOR KEY SHARE row locks in serializable mode
- Make sure "expanded" datums returned by a plan node are read-only
- Avoid crash in postgres -C when the specified variable has a null string value
- Prevent unintended waits for the receiver in WAL sender processes
- Fix possible loss of large subtransactions in logical decoding
- Fix failure of logical decoding when a subtransaction contains no actual changes
- Ensure that backends see up-to-date statistics for shared catalogs

- Avoid consuming a transaction ID during VACUUM
- Prevent possible failure when vacuuming multixact IDs in an installation that has been pg_upgrade'd from pre-9.3
- When a manual ANALYZE specifies a column list, don't reset the table's changes_since_analyze counter
- Fix ANALYZE's overestimation of n_distinct for a unique or nearly-unique column with many null entries
- Prevent autovacuum from starting multiple workers for the same shared catalog
- Fix bug in b-tree mark/restore processing
- Avoid duplicate buffer lock release when abandoning a b-tree index page deletion attempt
- Fix building of large (bigger than shared_buffers) hash indexes
- Prevent infinite loop in GiST index build for geometric columns containing NaN component values
- Fix possible crash during a nearest-neighbor (ORDER BY distance) indexscan on a contrib/btree_gist index on an interval column
- Fix "PANIC: failed to add BRIN tuple" error when attempting to update a BRIN index entry
- Fix possible crash during background worker shutdown
- Fix PL/pgSQL's handling of the INTO clause within IMPORT FOREIGN SCHEMA commands

- Teach libpq to correctly decode server version from future servers
- Fix ecpg's code for unsigned long long array elements
- In pg_dump with both -c and -C options, avoid emitting an unwanted CREATE SCHEMA public command
- Improve handling of SIGTERM/control-C in parallel pg_dump and pg_restore
- Fix error reporting in parallel pg_dump and pg_restore
- Ensure that parallel pg_dump or pg_restore on Windows will shut down properly after an error
- Make parallel pg_dump fail cleanly when run against a standby server
- Make pg_dump behave better when built without zlib support
- Make pg_basebackup accept -Z 0 as specifying no compression
- Fix makefiles' rule for building AIX shared libraries to be safe for parallel make
- Fix TAP tests and MSVC scripts to work when build directory's path name contains spaces
- Be more predictable about reporting "statement timeout" versus "lock timeout"
