Perhaps --with-segsize-blocks is a better name here as we use block instead of page for --with-blocksize and --with-wal-blocksize. If this option is for dev/debug purposes only, do we want to put a mechanism to disallow it in release builds or something like that, just in case? Or at least, add a note in the documentation? -- Bharath Rupireddy PostgreSQL Contributors Team RDS Open Source Databases Amazon Web Services: https://aws.amazon.com
