Currently it is considered similar to SET statement as it performs
similar operation except that the value for configuration gets set
in configuration file.  Do you see any reason for it to be considered
differently except that the command has ALTER keyword?

Note-
Initially we have thought it to be a variant of SET (SET PERSISTENT),
however later it turns out that it will be better to use ALTER SYSTEM
for this command.
