Is there a step by step procedure how to install the jdbc connector to sql developer? I tried to follow the PostgreSQL documentationbut with no luck.

You can't just runa JDBC driver as if it was an executable JAR.
您不能像运行可执行 JAR一样运行JDBC 驱动程序。
java -jar postgresql-9.3_1100.jdbc41.jar
will produce the error:
会产生错误：
no main manifest attribute in postgresql-9.3_1100.jdbc41.jar
because it has no mainmanifest attribute in the jar. That's because you're not supposed to run it.
因为它main在 jar 中没有manifest 属性。那是因为你不应该运行它。
Install the JDBC driver, like any other JDBC driver, according to the instructions for your application. See "Oracle SQL Developer" install JDBC driver.
根据应用程序的说明安装 JDBC 驱动程序，就像安装任何其他 JDBC 驱动程序一样。请参阅“Oracle SQL Developer”安装 JDBC 驱动程序。
The above search finds instructions on installing 3rd party (non-Oracle) JDBC driversand "Configure JDBC in Oracle JDBC driver". I strongly suggest following those instructions.
上述搜索找到有关安装 3rd 方（非 Oracle）JDBC 驱动程序和“在 Oracle JDBC 驱动程序中配置 JDBC”的说明。我强烈建议遵循这些说明。
In future, please explain step by step what you've done when you're having a problem, where you get stuck, and what you expect to happen instead.
以后，请逐步解释您在遇到问题时做了什么，遇到了什么问题，以及您希望发生什么。
P.s. I've submitted a patch to PgJDBC so that when you try this in future, it'll give you an informative error. See https://github.com/pgjdbc/pgjdbc/pull/112
Ps 我已经向 PgJDBC 提交了一个补丁，所以当你以后尝试这个时，它会给你一个信息性错误。见https://github.com/pgjdbc/pgjdbc/pull/112
