Changelog

Notable changes since version 42.0.0, read the complete History of Changes.

The format is based on Keep a Changelog.

Unreleased

Changed

Added

  • Verify code via forbidden-apis (jdk-internal and jdk-non-portable signatures) PR #2012

Fixed

  • Fix "Required class information missing" when old org.jboss:jandex parses pgjdbc classes [issue 2008][pgjdbc#2008]
  • Fix PGCopyInputStream returning the last row twice when reading with CopyOut API [issue 2016][pgjdbc#2016]

[42.2.18]

Fixed

  • Unfortunately changing the default of gssEncMode to ALLOW was not enough. The GSSEncMode Enum was not changed as well fixed in #1920

[42.2.17]

Changed

  • Change default of gssEncMode to ALLOW. PostgreSQL can deal with PREFER but there are cloud providers that did not implement the protocol properly. Libpq gets around this by checking for a GSS credential cache before attempting the connection. This is possible in JDK 8 and up, but not JDK6, or JDK7 fixes Issue #1868 PR #1913

Added

Fixed

  • Avoid NullPointerException when receiving PGbox, PGcircle, PGline, PGlseg, PGpath, PGpoint, PGpolygon, and PGmoney [PR 1873] (pgjdbc#1873).
  • The driver returns enum and jsonb arrays elements as String objects (like in 42.2.14 and earlier versions) PR 1879.
  • PgTokenizer was ignoring last empty token PR #1882
  • Remove osgi from karaf fixes Issue #1891 PR #1902

42.2.16 (2020-08-20)

Known issues

  • The driver returns enum and jsonb arrays elements are returned as PGobject instances (fixed in 42.2.17)

Fixed

  • Arrays sent in binary format are now sent as 1 based. This was a regression for multi-dimensional arrays as well as text/varchar, oid and bytea arrays. Since 42.2.0 single dimensional arrays were stored 0 based. They are now sent 1 based which is the SQL standard, and the default for Postgres when sent as strings such as '{1,2,3}'. Fixes issue 1860 in PR 1863.

42.2.15 (2020-08-14)

Changed

  • Rename source distribution archive to postgresql-$version-jdbc-src.tar.gz, and add top-level archive folder ba017507
  • Add the ability to connect with a GSSAPI encrypted connection. As of PostgreSQL version 12 GSSAPI encrypted connections are possible. Now the driver will attempt to connect to the server with a GSSAPI encrypted connection. If that fails then attempt an SSL connection, finally falling back to a plain text connection. All of this is controlled using both the gssEncMode and sslMode parameters which, in concert with pg_hba.conf, determine if a particular mode is allowed and or required. PR 1821 ad921b9e
  • Source release archive shades dependencies (scram) by default. It affects only postgresql-version-src.tar.gz release artifact f0301eb9
  • Refactor decoding arrays PR 1194

Added

  • Verify nullness with CheckerFramework 6e524ae5

Fixed

  • Avoid preparedStatement leak when using updateable ResultSet via insert/update/refreshRow PR 1815 9a0d2b18
  • Change order of checks for oid vs primary keys. OID's have been deprecated. PR 1613
  • Close certificate file stream. PR 1837
  • Make sure socketTimeout is enforced PR 1831
  • Assume PKCS-8 SSL key format by default PR 1819
  • Preserve unquoted unicode whitespace in array literals PR 1266

42.2.14 (2020-06-10)

Changed

  • Reverted com.github.waffle:waffle-jna, org.osgi:org.osgi.core, org.osgi:org.osgi.enterprise dependencies to optional=true in Maven PR 1797.

42.2.13 (2020-06-04)

Notable Changes

  • Security: The primary reason to release this version and to continue the 42.2.x branch is for CVE-2020-13692. Reported by David Dworken, this is an XXE and more information can be found here. Sehrope Sarkuni reworked the XML parsing to provide a solution in commit 14b62aca4.
  • The build system has been changed to Gradle thanks to Vladimir PR 1627.
  • Regression: com.github.waffle:waffle-jna, org.osgi:org.osgi.core, org.osgi:org.osgi.enterprise dependencies are listed as non-optional issue 1975.

Changed

Added

42.2.12 (2020-03-31)

Notable changes

We have released 42.2.12 to correct regressions in this version: Specifically

  • PR 1719 has been reverted as it introduced errors in the PgType Cache

We recommend that version 42.2.11 not be used.

  • reverted PR 1719 add support for full names of data types (#1719)

42.2.11 (2020-03-07)

  • Avoid reflective access to TimeZone.defaultTimeZone in Java 9+ PR 1002 fixes Issue 986

42.1.2 (2017-07-12)

  • Better logic for returning keyword detection. Previously, pgjdbc could be defeated by column names that contain returning, so pgjdbc failed to "return generated keys" as it considered statement as already having returning keyword PR 824 201daf1d
  • Use server-prepared statements for batch inserts when prepareThreshold>0. Note: this enables batch to use server-prepared from the first executeBatch() execution (previously it waited for prepareThreshold executeBatch() calls) abc3d9d7

Fixed

  • Replication API: fix issue in #834 setting statusIntervalUpdate causes high CPU load. PR 835 59236b74

Regresions

  • NPE in PreparedStatement.executeBatch in case of empty batch. Fixed in 42.1.3

42.1.1 (2017-05-05)

Fixed

  • Fix infinite dates that might be corrupted when transferred in binary for certain JREs. For instance, 5881610-07-11 instead of infinity. 1e5bf563

42.1.0 (2017-05-04)

Added

  • Support fetching a REF_CURSOR using getObject PR 809

Fixed

  • Fix data being truncated in setCharacterStream (bug introduced in 42.0.0) PR 802

  • Make sure org.postgresql.Driver is loaded when accessing though DataSource interface Issue 768

Regressions

  • There's no 42.1.0.jre6 version due to infinity handling bug. Fixed in 42.1.1.jre6

42.0.0 (2017-02-20)

Added

Changed

  • Version bumped to 42.0.0 to avoid version clash with PostgreSQL version and follow a better sematic versioning. 46634923
  • Ensure executeBatch() can be used with pgbouncer. Previously pgjdbc could use server-prepared statements for batch execution even with prepareThreshold=0. Issue 742
  • Error position is displayed when SQL has unterminated literals, comments, etc. Issue 688
  • Strict handling of accepted values in getBoolean and setObject(BOOLEAN), now it follows PostgreSQL accepted values, only 1 and 0 for numeric types are accepted (previously !=0 was true). PR 732
  • Return correct versions and name of the driver. PR 668

Removed

  • Support for PostgreSQL versions below 8.2 was dropped. PR 661

Deprecated

  • Deprecated PGPoolingDataSource, instead of this class you should use a fully featured connection pool like HikariCP, vibur-dbcp, commons-dbcp, c3p0, etc. PR 739

Regressions

  • Data truncated in setCharacterStream. Fixed in 42.1.0
  • No suitable driver found for jdbc:postgresql when using a DataSource implementation. Fixed in 42.1.0
