- tempmatviews-v2.patch (text/x-patch) patch v2
Hi! I made a new version of the patch. I added tests and changes to the docs and made sure various other aspects of this change for as well. I think this now makes temporary materialized views fully implemented and that in my view patch is complete. If there is anything else to add, please let me know, I do not yet have much experience contributing here. What are next steps? Do I just wait for it to be included into Commitfest? Do I add it there myself?
