Problem in PostgreSQL JDBC documentation file

Good Afternoon,

I'm trying to download the JDBC drive documentation for PostgreSQL
url:

https://jdbc.postgresql.org/documentation/documentation.html

However, the archive postgresql-jdbc-head-doc.tar.gz is empty.

Even though there is a link in equerda which also shows the manuals
need to download the files locally, you can check what's going on?

I'm waiting and I thank you for your attention.

Regards,

Misael C. Homem
