42.2.0 (2018-01-17)

Known issues

• SCRAM does not work as scram:client library is not packaged
• client_encoding has to be UTF8 even with allowEncodingChanges=true

Added

• Support SCRAM-SHA-256 for PostgreSQL 10 in the JDBC 4.2 version (Java 8+) using the Ongres SCRAM library. PR 842
• Make SELECT INTO and CREATE TABLE AS return row counts to the client in their command tags. Issue 958 PR 962
• Support Subject Alternative Names for SSL connections. PR 952
• Support isAutoIncrement metadata for PostgreSQL 10 IDENTITY column. PR 1004

• Implement support for get/setNetworkTimeout() in connections. PR 849
• Make GSS JAAS login optional, add an option "jaasLogin" PR 922 see Connecting to the Database

Changed

• Improve behaviour of ResultSet.getObject(int, Class). PR 932
• Parse CommandComplete message using a regular expresion, allows complete catch of server returned commands for INSERT, UPDATE, DELETE, SELECT, FETCH, MOVE, COPY and future commands. PR 962
• Use 'time with timezone' and 'timestamp with timezone' as is and ignore the user provided Calendars, 'time' and 'timestamp' work as earlier except "00:00:00" now maps to 1970-01-01 and "24:00:00" uses the system provided Calendar ignoring the user-provided one PR 1053

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

Fixed

• Make warnings available as soon as they are received from the server. This is useful for long running queries, where it can be beneficial to know about a warning before the query completes. PR 857
• Use 00:00:00 and 24:00:00 for LocalTime.MIN/MAX. PR 992
• Now the DatabaseMetaData.getFunctions() implementation complies with the JDBC docs. PR 918

• Received resultset tuples, but no field structure for them" when bind failure happens on 5th execution of a statement Issue 811

Removed

• Drop support for the (insecure) crypt authentication method. PR 1026

Deprecated

• Reintroduce Driver.getVersion for backward compatibility reasons, mark it as deprecated as application should not rely on it (regression since 42.0.0) 50d5dd3e

42.1.4 (2017-08-01)

Changed

• Statements with non-zero fetchSize no longer require server-side named handle. This might cause issues when using old PostgreSQL versions (pre-8.4)+fetchSize+interleaved ResultSet processing combo. Issue 869

42.1.3 (2017-07-14)

Fixed

• Fix NPE in PreparedStatement.executeBatch in case of empty batch (regression since 42.1.2). PR 867

42.1.2 (2017-07-12)

Changed

• 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
• Fix calculation of lastReceiveLSN for logical replication PR 801
• 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

• Replication protocol API was added: replication API documentation. PR 550
• java.util.logging is now used for logging: logging documentation. PR 722
• Add support for PreparedStatement.setCharacterStream(int, Reader). ee4c4265

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
