我在 Windows Server 2022 Standard 上运行 Postgres 14。在执行数据库操作（例如插入）时，我的服务器重新启动，现在 Postgres 无法启动。我查看了配置文件，其中最后几行如下：

此外，根据其他人的建议，我检查了事件查看器并看到：
2023-04-23 03:33:39.610 PDT [5804] FATAL: configuration file "C:/Program Files/PostgreSQL/14/data/postgresql.conf" contains errors
由于我使用 psycopg 来处理数据库，因此出现以下错误：
File "C:\Python310\lib\site-packages\psycopg2\__init__.py", line 122, in connect
conn = _connect(dsn, connection_factory=connection_factory, **kwasync)
sqlalchemy.exc.OperationalError: (psycopg2.OperationalError) connection to server at "localhost" (::1), port 5432 failed: Connection refused (0x0000274D/10061)
Is the server running on that host and accepting TCP/IP connections?
connection to server at "localhost" (127.0.0.1), port 5432 failed: Connection refused (0x0000274D/10061)

由于大小限制，我删除了所有评论：
listen_addresses = '*' # what IP address(es) to listen on;
port = 5432 # (change requires restart)
max_connections = 100 # (change requires restart)
shared_buffers = 4096MB # min 128kB
work_mem = 2000MB # min 64kB
maintenance_work_mem = 3000MB # min 1MB
dynamic_shared_memory_type = windows # the default is the first option
max_wal_size = 1GB
min_wal_size = 80MB
effective_cache_size = 4GB
log_destination = 'stderr'
logging_collector = on # Enable capturing of stderr and csvlog
log_timezone = 'America/Los_Angeles'
datestyle = 'iso, mdy'
timezone = 'America/Los_Angeles'
lc_messages = 'English_United States.1252' # locale for system error message
# strings
lc_monetary = 'English_United States.1252' # locale for monetary formatting
lc_numeric = 'English_United States.1252' # locale for number formatting
lc_time = 'English_United States.1252' # locale for time formatting
default_text_search_config = 'pg_catalog.english'
我没有最近的数据库备份。我该如何解决这个问题？

感谢@Nikita Kipriyanov，通过从另一个安装中替换新的配置文件解决了该问题。
