If you use screen(1) and detach from it, then reattach to it at a
later date, there may be some diagnostic output sent to the screen.

# Start work
ssh....
screen -d -R -S psql
psql...
Ctrl-a d
exit

# Come back a few hours later:
ssh....
screen -d -R -S psql
[check to see if there's any output]
exit  # the screen session
exit  # exit ssh
