Not only as part of "CREATE FUNCTION", but as part of "ALTER
DATABASE", "ALTER ROLE", "ALTER FUNCTION" syntax as well. In all these
places other syntax of "SET" is also used and described.
I think you are right that syntax <SET .. FROM CURRENT> is mainly used
in context with few other SQL statements, but as it is part of SET
command, so isn't it better to mention the syntax on SET page and may
be explain a bit about its usage?

After explaining the usage in short, may be can provide links to
all other statements where it can be used, but I think syntax <SET ..
FROM CURRENT> should be there with SET command's other syntax.
