This might be interesting to do, and we could tie it into the need to
invalidate PL/PgSQL functions that depend on a database object when
the object is changed.
Perhaps when the function is defined, we run all the SQL queries in
the function body through the parser/analyzer/rewriter, and then
generate dependencies on the Query trees we get back?
In any case, there would be a limit to what we could divine from the
function definition (e.g. we'd get practically no info about a
function defined in C) -- but this might make things a little nicer,
anyway.
Cheers,
Neil
