It's been a while since the last PL/Java beta5 and a new PostgreSQL
8.0.0rc1 was just released. This seemed to be a good time to make the
next PL/Java release. The new release is called beta6 since several new
features where added:
* Savepoint support
Awaiting full savepoint support from the PostgreSQL SPI layer, a
temporary but well functioning layer of functions was implemented in
PL/Java. The implementation prevents that a savepoint can live longer
than the function where it was set and that it cannot be released or
rolled back inside a nested function. The savepoint functionality
requires PostgreSQL 8.0.0rc1 or later.
* SETOF functions can now return a set of a scalar type, i.e. SETOF int
Previously, PL/Java could only return SETOF <complex type>. Now, a
static method returning a java.util.Iterator can be used as a function
returning SETOF <scalar type>
* ExecutionPlan pooling
PL/Java will make more effective use of prepared execution plans through
an LRU cache implementation.
* ClassLoader based resource retrieval
The real resource support that was lacking in the internal PL/Java
ClassLoader has now been added. This means that jar files loaded using
install_jar/replace_jar may contain files that can be accessed using the
getResource and getResourseAsStream on the Class and ClassLoader classes.
PL/Java source and ports for Win32 and Linux x86 can be found at
