The fix is:

The problem:
How to recreate the problem.  (You know - QA).

Upstream you said:

"This has been working for years on all PG community servers.

This happens on an EDB PG 9.6.3."

Which version of the EDB Postgres database are you using e.g. their install of the community version or their modified(Advanced?) version?

When I search on CMS_SYSPRM it comes related to bmc.com, is that in the mix also?



Tried changing lc_time, timezone and datestyle .. but nothing seems to work

Thanks

Danny

Thanks Andrew.

My code fails since the expression (In a PG/PG SQL function) which
assumes integer result Now produces the string '8 day';

The code is?

I know the fix, but I need the ability to create the bug in my server, and I do not know how.

Thanks

No, it'll always return an integer. You will only get an interval result if you subtract timestamps rather than dates, for example if one of the operands is actually an expression returning a timestamp.

Give an example of an actual expression you used that returned an interval instead, and we may be able to tell you how to fix it.
