Servicename: postgresql-x64-16
Name:        postgresql-x64-16-PostgreSQL Server 16
Comment:     Provides relational database storage
Path:        "C:\PRGS\pgSQL\16\bin\pg_ctl.exe"
              runservice -N "postgresql-x64-16"
              -D "C:\DB\pgSQL\16\data" -w
Type:        Automatic
Account:     Networkservice
Password:    set
Dependencies:RPC, DCOM-Service, RPC-Endpoint

Errors found within system logs:
pg_ctl: could not find program 'postgres.exe'

Seems, since "C:\PRGS\pgSQL\16\bin" is in system path, it does not 
search there at all:

# dir "C:\PRGS\pgSQL\16\bin"
[...]
Mi, 13.Nov.2024  13:24           123.392 pg_ctl.exe
[...]
Mi, 13.Nov.2024  13:24         8.659.968 postgres.exe

Any way to tell a service in Windows to use a path?
Any registry key to assign a path to?

# sc qc "postgresql-x64-16"
