PL/Java brings functions, triggers, aggregates, types, operators, etc. in Java.

1.6.4 is the fourth 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.

1.6.4 is a minor bug-fix release with few other notable changes. Further information on the changes may be found below.

Upcoming changes in Java beyond version 17 will affect PL/Java. For more on those changes and how PL/Java will adapt, please bookmark JEP 411 on the PL/Java wiki.

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.

Selected changes

• The recently-added support for functions with OUT parameters now generates the correct SQL declaration for a function with one OUT parameter.
