How to change/set the block size in Postgres? Is there any file to make the configuration?

问题

I'm looking for the BLOCKSIZE configuration in postgres. I want to know is there a way to change/set the value?

回答1:

In PostgreSQL v11, you can do that when you create the cluster:

initdb --wal-segsize=<size in MB> [other options]

In older versions of PostgreSQL, you have to recompile after configuring with

./configure --with-wal-segsize=<size in MB>

This is no runtime configuration.

https://www.postgresql.org/docs/current/storage-page-layout.html

Every table and index is stored as an array of pages of a fixed size (usually 8 kB, although a different page size can be selected when compiling the server).
