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/17895.1315869622@sss.pgh.pa.us
so， It is best to add this description to the document about work_mem and maintenance_work_mem parameter
