Semab Tariq continues a series on Postgres internals:
Welcome to the second part of our PostgreSQL internals blog series. In the first part, we delved into database clusters and their physical structure.
In part two, we’ll explore the internal structure of a page in PostgreSQL. If you still need to check out part one, you can find it here.
A lot of this is similar to SQL Server, though it’s not quite the same.
