DO currently is a utility command, not a query. Do you mean to change that? Also, did you think about a lambda construct, which is basically allowing functions to be defined inline in a query? We could imagine several syntax to show up the idea, common keywords here include LAMBDA, FLET or LABELS, but I think that expanding WITH would be preferable for us. WITH FUNCTION foo(param list) returns rettype language foo AS ( definition here ) <query using foo() here>; Other WITH extensions we can think about include support for DCL as asked by David Fetter in the past already, and support for variables too (a kind of per-query SET LOCAL). I don't see how adding parameters and return values to utility commands is going to be easier than adding a "lambda" facility.
