There are several possible values of context. In order of decreasing
difficulty of changing the setting, they are:
...
superuser-backend
Changes to these settings can be made in postgresql.conf without
restarting the server. They can also be set for a particular session in
the connection request packet (for example, via libpq's PGOPTIONS
environment variable), but only if the connecting user is a superuser or
has been granted the appropriate SET privilege. However, these settings
never change in a session after it is started. If you change them in
postgresql.conf, send a SIGHUP signal to the postmaster to cause it to
re-read postgresql.conf. The new values will only affect
subsequently-launched sessions.
