Re: Different results from identical matviews

[Jeremy Smith]

It looks like you are using now() fairly often in that query.  That would,
of course, give different results in different transactions, but it could
also give different results if a) the things you are comparing now() to are
timestamp without time zone and b) the session time zone of the user doing
the refresh is different from the session time zone of the user running the
query.  I'd also be suspicious about any other timestamp comparisons that
aren't comparing timestamp to timestamp or timestamptz to timestamptz.
