Make shared_memory_size a preset option

michaelpq · michaelpq · commit 3b231596ccfc · 2021-09-09T09:57:28.000+09:00
bd17880 set up that as a memory parameter, but the docs told a different story. A preset parameter is adapted here, as this option is compiled at startup time. Reported-by: Fujii Masao Discussion: https://postgr.es/m/4cc5b434-b174-9aae-197b-737db6cac4e3@oss.nttdata.com
