Release Notes

pgjdbc/pgjdbc (org.postgresql:postgresql)

v42.7.12

Security

Added

• feat: reWriteBatchedInserts now merges up to 32768 rows into one multi-values INSERT (bounded by the 65535 bind-parameter limit on the extended protocol) instead of capping at 128, which speeds up batches of few-column rows. The new reWriteBatchedInsertsSize connection property lowers that cap when set; the default of 0 uses that maximum.
• feat: invalidate the prepared-statement cache after CREATE/DROP/ALTER so callers no longer trip on "cached plan must not change result type" without opting into autosave=ALWAYS. Controlled by the new flushCacheOnDdl connection property (default true); set to false for the prior behaviour.
• feat: add connectExecutor connection property to customize the Executor used to run the worker task that performs the connection attempt when loginTimeout is in effect. The value is the fully qualified name of a class implementing java.util.concurrent.Executor. With a null value, the default, the driver retains the prior behavior of running the connection attempt on a daemon thread named "PostgreSQL JDBC driver connection thread". The executor must run the task on a thread other than the caller's. Running the attempt on a named thread lets applications that monitor driver-created threads identify it.
• feat: add connectThreadFactory connection property to customize the ThreadFactory used to spawn the worker thread that runs the connection attempt when loginTimeout is in effect. The value is the fully qualified name of a class implementing java.util.concurrent.ThreadFactory. With a null value, the default, the driver retains the prior behavior of using a daemon thread named "PostgreSQL JDBC driver connection thread". Useful for testing timeout behaviour or for applications that want detailed control of all driver-created threads.
• feat: add classLoaderStrategy connection property to control which classloaders the driver searches when loading a class named by a connection property, for example socketFactory. The default driver-first now falls back to the thread context classloader when the driver's classloader cannot resolve the class, which fixes class loading in non-flat class paths such as Quarkus and OSGi. Set driver to keep the previous driver-classloader-only behaviour, or context-first to prefer the thread context classloader Issue #​2112

Changed

• refactor: the worker that runs the connection attempt under loginTimeout is now a FutureTask (ConnectTask) instead of the hand-rolled ConnectThread. When the caller hits the timeout, the task is now cancelled with cancel(true), which interrupts the worker thread rather than letting it run to completion. This makes the connection attempt interruptible, so loginTimeout can stop a slow connection attempt instead of leaking a thread. As before, a connection that the worker still manages to establish after the caller gives up is closed by the worker so that it does not leak. There are no public API changes and this should only lead to faster background resource cleanup for connections that time out.
• chore: PGXAConnection.ConnectionHandler now rejects setAutoCommit(false) and setSavepoint(...) during an active XA branch, in addition to the long-rejected setAutoCommit(true) / commit() / rollback(). The setSavepoint rejection was already meant to be in place but the guard misspelled the method name as setSavePoint, so savepoints silently went through. Both changes bring the proxy in line with JTA 1.2 §3.4.
• chore: commitPrepared / rollback-of-prepared now return XAER_RMFAIL instead of XAER_RMERR when the underlying connection is left in a non-idle TransactionState. Transaction managers (Geronimo, Narayana, Atomikos) treat XAER_RMFAIL as retryable on a fresh XAResource; the prepared transaction is no longer abandoned.

Fixed

• fix: the published GitHub release now ships the released postgresql-<version>.jar and its detached PGP signature, taken from the same signed build that is uploaded to Maven Central, instead of a leftover SNAPSHOT jar Issue #​3812 PR #​3814
• fix: simplify the Statement#cancel state machine by dropping the redundant CANCELLED state. killTimerTask now waits for the state to return to IDLE directly, which removes a spin-forever case when more than one thread observes the cancel completing PR #​1827.
• perf: defer simple-query flushes until the driver reads the response, allowing BEGIN and the following query to share a network flush Issue #​3894
• fix: reWriteBatchedInserts no longer throws IllegalArgumentException when batching a parameterless INSERT (for example INSERT INTO t VALUES (1, 2)) of 256 rows or more.
• fix: a comment before CALL in a CallableStatement no longer hides the native call, so OUT parameter registration works for /* comment */ call proc(?, ?) and similar. Parser.modifyJdbcCall now skips leading whitespace and SQL comments (both -- and /* */) before the call, tolerates a trailing comment after a { ... } escape, and no longer adds a spurious comma when moving an OUT parameter into a call whose arguments are only a comment Issue #​2538
• fix: PreparedStatement.toString() no longer throws for a bytea value supplied as text via PGobject. Hex-format values (\x...) are validated and rendered as a bytea literal, and escape-format values are quoted and cast like any other literal Issue #​3757
• fix: the driver no longer nulls the contextClassLoader of shared ForkJoinPool.commonPool() worker threads, which previously left unrelated tasks on those threads running with a null classloader Issue #​4155
• fix: getCharacterStream wraps String in StringReader PR #​4063
• fix: PGXAConnection no longer saves and restores the underlying connection's JDBC autoCommit flag. All XA-protocol SQL (BEGIN, PREPARE TRANSACTION, COMMIT, ROLLBACK, COMMIT PREPARED, ROLLBACK PREPARED, the recover() SELECT) is sent through QUERY_SUPPRESS_BEGIN, so the caller's autoCommit value is invariant across every XAResource call. Fixes the "2nd phase commit must be issued using an idle connection" failure during recovery on managed datasources that pool connections with autoCommit=false (TomEE, WildFly, WebSphere Liberty).
• fix: PGXAConnection.prepare() now mutates XA state only after PREPARE TRANSACTION succeeds. A failed PREPARE previously left the driver thinking the branch was already prepared, so the follow-up rollback(xid) tried ROLLBACK PREPARED against a non-existent gid and returned XAER_RMERR. Transaction managers (Narayana) escalated this to HeuristicMixedException. With the fix, rollback(xid) takes the active-branch path and issues a plain ROLLBACK, which the server accepts cleanly. Fixes Issue #​3153, Issue #​3123.
• fix: an updatable result set over an unqualified table name is now classified using only the table visible through search_path. When two schemas held a table with the same name and the same primary or unique index name but a different set of key columns, the driver took the union of both schemas' columns, so the result set could be wrongly rejected as not updatable PR #​4214. Supersedes PR #​3400.

v42.7.11

Security

• fix: Limit SCRAM PBKDF2 iterations accepted from the server.
  pgjdbc was vulnerable to a client-side denial of service in SCRAM-SHA-256 authentication, where a malicious or compromised PostgreSQL server could specify an extremely large PBKDF2 iteration count, causing the client to consume unbounded CPU and potentially exhaust connection pools. The fix introduces a new scramMaxIterations connection property (defaulting to 100,000) to cap iteration counts before computation begins.
  See the Security Advisory for more detail.
  The following CVE-2026-42198 has been issued.
