log4net输出到PostgreSql

PgSQL越来越强大了。小项目输出log到sqlite是挺好的，大东西尤其是要长期运行的程序还是输出到PostgreSQL比较，也更适用于寄宿在Windows Service这种将当前目录视为System32的场合。

直接上配置文件。

<!--定义输出到PostgreSql数据库中，用于Windows Service这种无法正确识别程序当前目录从而无法使用相对路径的场合-->
    <appender name="AdoNetAppender_PostgreSQL_All" type="log4net.Appender.AdoNetAppender">
      <bufferSize value="10"/>
      <connectionType value="Npgsql.NpgsqlConnection, Npgsql"/>
      <!--PostgreSql连接字符串-->
      <connectionString value="Server=127.0.0.1;Port=5432;User Id=postgres;Password=tm;Database=postgres;"/>
      <!--PostgreSql插入字符串-->
      <!--如果想在PostgreSql中保持字段字有大小写，要加入"
          但是由于我用了Ormlite，所以不需要了

运行时当前目录下要有Npgsql.dll，还要事先在PgSQL中建好表，好人做到底，再奉上Ormlite生成的SQL：

-- Table: log

-- DROP TABLE log;

CREATE TABLE log
(
  id serial NOT NULL,
  date_time timestamp without time zone NOT NULL,
  thread text,
  level text,
  logger text,
  message text,
  exception text,
  stack_trace_detail text,
  location text,
  identity text,
  app_domain text,
  user_name text,
  ndc text,
  utc_date timestamp without time zone,
  aspnet_cache text,
  aspnet_context text,
  aspnet_request text,
  aspnet_session text,
  CONSTRAINT log_pkey PRIMARY KEY (id)
)
WITH (
  OIDS=FALSE
);
ALTER TABLE log
  OWNER TO postgres;

-- Index: idx_log_level

-- DROP INDEX idx_log_level;

CREATE INDEX idx_log_level
  ON log
  USING btree
  (level COLLATE pg_catalog."default");

-- Index: uidx_log_date

-- DROP INDEX uidx_log_date;

CREATE UNIQUE INDEX uidx_log_date
  ON log
  USING btree
  (date);

发完贴子才发现系统将"给解析成了双引号，再直接贴上：
