Based on comments in include/catalog/genbki.h and the way most PostgreSQL catalogs are defined, variable length catalog fields should be in the end of the definition and hidden. We need to integrate this rule into our distributed system catalogs Aperta

In worker_partition_protocol.c, we have a range repartition and a hash repartition function. These functions are asymetric in terms of how they bucket Null values. Making them symmetric is important in the context of Left and Right outer joins. Aperta

We ran code coverage with our regression tests. We found out that MasterAggregateMutator and WorkerAggregateWorker on Var input didn't get called at all. If we don't need this code path, we should remove it Aperta

Approximate count(distinct) queries use hll as their intermediate data type. We have a mismatch between hll target entry and sort clause's sortop oid, so we can't push an order by on the hll data type to worker nodes. Aperta
