I have a problem for which a view seems like a nice solution. Basically we want to see all records in some table that are older than 5 days and haven't yet gone through further processing.
This particular view is probably simple enough that it doesn't require unit tests but I wonder how people test complex views that depend on the current date or time. I found a thread on the hackers list [1] that talked about stubbing pg_catalog.now() but was wondering if any TDD minded developers had invented anything better since then.
One option I thought of was to just not use views that depend on the current date or time and instead create a set returning function that takes the time as a parameter. Would such a function have similar performance characteristics to an equivalent view?
