pg document is not recorded:maintenance_work_mem can not large than 2GB in windows。
https://www.postgresql.org/docs/14/runtime-config-resource.html I suggest that:modify maintenance_work_mem parameter description in the pg documents: add maintenance_work_mem parameter size limit in windows platform if you set maintenance_work_mem large that 2GB in windows platform postgresql service can not start。 in the windows event viewer ,thare is the following error: "ERROR: 3072000 is outside the valid range for parameter "maintenance_work_mem" (64 .. 2097151) and the work_mem parameter also has similar problems as above。 https://www.postgresql.org/message-id/17895.1315869...@sss.pgh.pa.us so, It is best to add this description to the document about work_mem and maintenance_work_mem parameter
