We've agreed that the factory default should be "error", but I don't
think we can go much further than that in the direction of breaking
peoples' code. We need to provide a backwards-compatible option,
IMHO, so that this isn't seen as a roadblock to updating to 8.5.
(You can argue all you want about whether it really is one, but it'll
be seen as one.) And the Oracle-compatible option will be attractive
to people coming in from that side. Reviewing megabytes of pl/sql
code for this kind of gotcha is not fun, and the "error" default would
only help a bit.
One advantage of making the GUC be SUSET is that those who want to take
a paranoid approach here have an easy answer: don't allow it to be
changed from "error". We are allowed to assume that those who do change
it are responsible adults.
