which might not be what you need. the problem is that there is no
guarantee that the last "accessed" file is the current one.

on the other hand - there is also no such guarantee for current being
"last after sorting", so there is a room for failure here anyway.

the only way to do it without having problems with "strange" names or
dates of access:

ps uw -C postgres | grep logger | awk '{print "/proc/"$2"/fd"}' | xargs ls -l | grep /var/log/postgresql | awk '{print
$NF}'| xargs tail -f 

but it has its own set of problems ranging from "being totally
unreadable" to "requires running on postgres user or as root".

Best regards,
