This article details the process of moving specific tables from one PostgreSQL instance to another using logical replication. It covers granting access, copying schema, setting up publications and subscriptions, and handling sequences and indexes to minimize downtime.

The article discusses the temporal-spatial locality hypothesis in database design, highlighting its significance for optimizing performance in various database systems. It contrasts the behavior of streaming systems that benefit from this hypothesis with hash-based databases that do not, and explores the implications of different key assignment strategies on read and write performance. The author argues that while the hypothesis is often weakly true, its relevance varies across workloads and requires careful consideration in schema design.
