Subject: [PATCH] Merge pull request from GHSA-673j-qm5f-xpv8

Removes loggerFile and loggerLevel properties and defers to java.util.logging to
configure all logging in the driver. Users that previously specifyied custom
logging via those connection properties should change their applications to
instead configure via a java.util.logging properties file or system properties.

The properties and enum values are now deprecated and may be removed in a future
driver version.

+### Logging
+PgJDBC uses java.util.logging for logging.
+To configure log levels and control log output destination (e.g. file or console), configure your java.util.logging properties accordingly for the org.postgresql logger.
+Note that the most detailed log levels, "`FINEST`", may include sensitive information such as connection details, query SQL, or command parameters.
+
 #### Connection Properties
 In addition to the standard connection parameters the driver supports a number of additional properties which can be used to specify additional driver behaviour specific to PostgreSQL™. These properties may be specified in either the connection URL or an additional Properties object parameter to DriverManager.getConnection.
