Improving PostgreSQL: How to Overcome the Tough Challenges

Definitely agree with Branson's top 10 of challenges with PostgreSQL, especially #3: "Inefficient Replication That Spreads Corruption". Postgres WAL entries are always the bottleneck of a replication stream.

definitely seen issues in #1 with 32-bit transaction ID and also the problems with connections in PG, but we can sort of manage around these.

Does Yugabyte actually contribute to Postgres or just use their code?
