If we can do something like :

I say yes !
This strikes me as just highly un-SQL-like.
Someone could fairly easily write it for themselves in Plpgsql or C, but
it doesn't seem to me like something we should be doing.
I tend to agree with Noah's comment upthread:
But the syntax is a bandage for raw psql input remaining a hostile
environment for implementing the full range of schema changes. Switch to
submitting your SQL from a richer programming environment, and these additions
to core syntax cease to add much.
I think this goes a fortiori for Heath Robinson-like devices such as this.
