This has ran through my mind as an option - the project is a web 
application with php and postgres, but a number of factors involved makes 
it really undesirable to do this at the application level - to the point 
that its worth my while to learn pl/pgsql, perl, or tcl to avoid it - or 
possibly even C - none of which I know... yet :)

So I repeat the question, not to be obnoxious - but to be sure, "does 
anyone *know* if any of the languages available for writing functions would 
allow a field name to be referenced using a variable as all or part of the 
field name?
