1.6.3 is the third minor update in the 1.6 series, for applications on PostgreSQL 9.5 or later and Java 9 or later. Legacy applications requiring older PostgreSQL or Java versions are supported by the 1.5 series.

1.6.3 adds support for PostgreSQL 14, brings a few improvements to the annotation-driven SQL generator and the runtime, and fixes several bugs. It also begins preparation for the impact of changes to Java's permission enforcement coming in Java 17 and later with JEP 411.

Selected changes

• Can generate a complete family of cross-type operators related by commutation and negation from a single Java method. A bug kept that from working in 1.6.2.

• A method parameter can now be annotated so that the PostgreSQL function parameter will default to null. Formerly, only non-null defaults could be specified that way.

• The current thread's context class loader now has a useful value on entry to a PL/Java function.

PL/Java 1.5.8 announced

PL/Java brings functions, triggers, and types in Java. The 1.5 series supports legacy applications, with PostgreSQL support extending from 14 back to 8.2, and Java back to 8 (7 or 6 with some extra build effort). Its build system targets Java no later than 14, but once built, it can run on later versions.

For applications on PostgreSQL 9.5 or later and Java 9 or later, please consider the more actively developed PL/Java 1.6 series.

1.5.8 brings support for PostgreSQL 14, and fixes two bugs. It also begins preparation for the impact of changes to Java's permission enforcement coming in Java 17 and later with JEP 411.

For more on those upcoming changes in Java and how PL/Java will adapt, please read about JEP 411 on the PL/Java wiki.

PL/Java 1.6.2 (the Black Friday edition)

PL/Java brings functions, triggers, and types in Java.

1.6.2 is the second minor update in the 1.6 series, for applications on PostgreSQL 9.5 or later and Java 9 or later. Legacy applications requiring older PostgreSQL or Java versions are supported by the 1.5 series.

1.6.2 fixes two bugs (one of which was likely to be a blocker for many applications). It adds a 'trial' security policy, useful when migrating code from PL/Java 1.5 to identify permission grants that may be needed, and some minor but useful example functionality.

Current users of a 1.5.x release should also review the 1.6.0 release notes for changes that may require attention before updating to 1.6.x.

Project site: http://tada.github.io/pljava/
Release notes: http://tada.github.io/pljava/releasenotes.html

Selected changes

• A 'trial' security policy allows code under test to be run in a partially-enforcing mode to determine what permission grants, if any, may need to be added to the production policy.

• Example functions demonstrating Java's built-in XSLT 1.0 support have been polished to simplify using it for real work. 1.0 is very limited compared to current XSLT versions, but requires no separate download, and Java's implementation can call accessible Java methods and constructors, offering ways around some limits of strict XSLT 1.0.

  One useful stocking-stuffer that results is a simple function to indent XML for readability, just passing a null transform name and indent => true to transformXML.

PL/Java 1.6.1 announced

PL/Java brings functions, triggers, and types in Java.

1.6.1 is the first minor update in the 1.6 series, for applications on PostgreSQL 9.5 or later and Java 9 or later. Legacy applications requiring older PostgreSQL or Java versions are supported by the 1.5 series.

1.6.1 fixes two bugs in 1.6.0, and adds SQL generator support for aggregates, casts, operators, and function OUT parameters.

Current users of a 1.5.x release should also review the 1.6.0 release notes for changes that may require attention before updating to 1.6.x.

Project site: http://tada.github.io/pljava/
Release notes: http://tada.github.io/pljava/releasenotes.html

Selected changes

• OUT parameters offer one more way to declare functions returning composite types, with less burden on callers than RETURNS RECORD and less ceremony than declaring a named composite type.

• New Java source annotations @Aggregate, @Cast, @Operator further reduce the manual effort of maintaining SQL deployment scripts for the Java code.

PL/Java 1.5.7 announced

PL/Java brings functions, triggers, and types in Java. The 1.5 series supports legacy applications, with PostgreSQL support extending from 13 back to 8.2, and Java from 14 back to 8 (7 or 6 with some extra build effort).

1.5.7 is a pure bugfix release correcting one bug in XML Schema handling for some non-en_US locales. Its features are otherwise identical to 1.5.6.

For applications on PostgreSQL 9.5 or later and Java 9 or later, please consider the PL/Java 1.6 series.

PL/Java 1.6.0 announced

PL/Java brings functions, triggers, and types in Java.

1.6.0 is a notably refactored release that requires Java 9 or later and PostgreSQL 9.5 or later, and brings a number of changes from 1.5.x.

Current users of a 1.5.x release should review the 1.6.0 release notes for possibly necessary changes before updating to 1.6.0.

It includes configurable permissions (finer grained than just java versus javaU), a smarter SQL generator, and a much-improved build experience.

Project site: http://tada.github.io/pljava/
Release notes: http://tada.github.io/pljava/releasenotes.html

Selected changes

• The Java permissions available to java and javaU functions can be tailored for each case. Language 'aliases' beyond those two can also be set up with CREATE LANGUAGE and have their own associated permissions.

• The SQL generator no longer needs to be explicitly told about dependencies between a new type and the functions that use it, or are used in its implementation.

• PL/Java functions can now be variadic.

• The build system now takes pg_config values such as CFLAGS into account to match the compiler configuration used to build PostgreSQL.

• Two continuous integration services now routinely build PL/Java for Linux (x86_64 and ppc64le), Mac OS X, and Windows (MinGW-w64 and MSVC), with results visible at GitHub.
