Agroal/JDBC

The default maximum size of the JDBC connection pool has been raised from 20 to 50, to be more in line with modern standards.

If you relied on the default to be 20 (for instance, if you set the maximum connections to 20 on the database side), make sure to adapt your configuration or infrastructure.
