I see that it is mentioned in the documentation source (since Dec 2014, commit
31c5fcf9d620eb8403ec03682d8f90210da827f3), but I can't find it in the documentation
available on the web site.

Has the documentation on the web site been built recently?

I tried to build the documentation myself with "ant -lib lib doc", but it
failed with

java.io.FileNotFoundException: /path/to/pgjdbc/doc/${docbook.stylesheet} (No such file or directory)

Am I missing something?

Yours,
