log_line_info where this would be implemented is indeed done with a
printf like string, which is easily extensible The following is adapted
from the description of the original patch which it is my intention to
bring up to date soon and resubmit:

Prefixes each message in the server log file or syslog with extra
information as specified in the string. The default is an empty
string. The following sequences in the string are translated:
'%U' is replace with the username,
'%D' is replaced by the database name,
and '%%' is replaced by '%'.
All other characters are copied literally to the log. For example,
log_line_info = '<%U%%%D> '
will produce output like this:
<myuser%mydb> LOG: query: create table foo(blah text);
