That's pretty roundabout. We already expose (hex coded) pid.starttime as
a session identifier in log_line_prefix (it's the %c escape) so I don't
see any reason not to provide either the same thing directly in a
function, or at least to expose the backend pid.
That would be nice.

Hi, I cant find any function, which tells me something like session
id. Is there something like that? I need it in my AM, because I need
to know, if something which I wrote in file was written in this
current session or previously.
How about
select procpid||' '||backend_start from pg_stat_activi
