Thread: pgsql: tableam: Provide helper functions for relation sizing.
tableam: Provide helper functions for relation sizing. Most block-based table AMs will need the exact same implementation of the relation_size callback as the heap, and if they use a standard page layout, they will likely need an implementation of the relation_estimate_size callback that is very similar to that of the heap. Rearrange to facilitate code reuse. Patch by me, reviewed by Michael Paquier, Daniel Gustafsson, and Álvaro Herrera.
