Whether this is done via 1) compatibility layer or 2) migrating the

it in the compatibility layer is (maybe) lower risk when running on
Oracle. But, since we know there are many queries that must be
rewritten (for example: queries with the oracle (+) syntax for outer
joins) anyway, why not just do the right thing now and get it over with
while we're committed to spending the $$ and time to do this? If
satellite is going to become a multi-database application, shouldn't the
application code be as database agnostic as possible?
Agreed with the intention. But why is this part of the PostgreSQL
effort. Shouldn't this be completely independent goal, with its own
requirements and plan and test plan?
Maybe. I guess it depends on difference in effort required.
After the tagging process we need to count the #2 vs #3 queries (as
planned) and then decide which strategy make sense for us. Without
these numbers, we'll just be guessing the risk/reward of taking either
approach.
Agreed.
