Thank you for reporting the problem.

Sorry, multimaster code in this repository is slightly out of date (we included latest version of multimaster in Postgres Pro Enterprise Edition). We are going to update free version of multimaster, but it will take some time. Actually this bug is caused by my attempt to somehow synchronize code of repository. IndexRelationGetNumberOfKeyAttributes is function of PrPro EE, defined for covering indexes.
I fixed this build issue.
