Logging

PL/Java uses the standard java.util.logging.Logger Hence, you can write things like:

Logger.getAnonymousLogger().info( "Time is " + new Date(System.currentTimeMillis()));

At present, the logger is hardwired to a handler that maps the current state of the PostgreSQL configuration setting log_min_messages to a valid Logger level and that outputs all messages using the backend function ereport(). The following mapping apply between the Logger levels and the PostgreSQL backend levels:

java.util.logging.Level	PostgreSQL level
SEVERE	ERROR
WARNING	WARNING
INFO	INFO
FINE	DEBUG1
FINER	DEBUG2
FINEST	DEBUG3
