Well, in fact the error says that we internally try to mark a void column unique, which is not allowed and hence not done. Thus, there seems to be a bug that we incorrectly try to mark a void column unique, but since that fails, this is likely more an "annoying" than a crucial bug ...

hi, does the notification itself indicate anything important?
Internally incorrectly set (internal) BAT property. That might be crucial as we (internally) use properties to "cut corners" (aka. "optimize").
if people do not flush the logs, will any data be lost?
Should not --- the server flushes logs itself.
I just suggested for the purpose of reproducing this problem, to trigger the flush instead of waiting for the server to do it "eventually" and transparently in the background ...

thanks!

Hi,
I've just seen similar behavior, but failed so far to reliably reproduce it with a minimal test.
It seems requires at least creating a new DB with Oct2014, creating a table, inserting a least 2 tuples, stopping & restarting Oct2014 server to flush WAL logs, stopping Oct2014 server starting Jul2015 server to upgrade.
Best, Stefan

hi, i've just upgraded on my windows 8 laptop. every time i open the demo server, i get this GDK error below. it doesn't appear to have any effect when i run some simple queries. the error below does not appear when i create a fresh dbfarm elsewhere, it only happened on a database that's been upgraded.
any idea what's going on? thanks!

I have created a release candidate for the Jul2015 release. The candidate is available at http://dev.monetdb.org/downloads/testing/ . If all goes well, this candidate will morph into a release sometime soon(ish). In the mean time, you can use this release candidate and test to see whether it works. And if it doesn't work, I would really like to hear about it.
