Did you look at the commit message that introduced it?

commit e7889b83b7059e776f0a3d76bbbdd98687f4592c
Author: Tom Lane <tgl(at)sss(dot)pgh(dot)pa(dot)us>

Support SET FROM CURRENT in CREATE/ALTER FUNCTION, ALTER DATABASE, ALTER ROLE.
(Actually, it works as a plain statement too, but I didn't document that
because it seems a bit useless.) Unify VariableResetStmt with
VariableSetStmt, and clean up some ancient cruft in the representation of
same.
