+1. I'm really hoping to get something done about the plpgsql
parsing
situation before 8.5 is out, so this should be a dead end anyway.
I have a WIP patch for integration main SQL parser to plpgsql. I'll
send it to this weekend.
I certainly don't mind the patch getting rejected and agree that
refactoring the plpgsql parser is probably the best approach to this
issue. However, I think it would be more than a little strange to ship
the named notation feature without a solution for this problem. For
reference, the problem is that the function below causes a compile
error because of the way plpgsql blindly does variable replacement:
create function fun1(pDisplayName text) returns void as $$
begin
perform fun2(pDisplayName as pDisplayName);
-- Above line compiles as:
-- SELECT fun2( $1 as $1 )
end
$$ language plpgsql;
