I am working with Postgresql 9.3.4 source using eclipse IDE in ubuntu
14.04. I have a library file abc.so to be loaded at run time when
postgresql server starts. When I run the server with
"-D /home/rajmohan/projects/TPCH_database"
as argument in run configuration, I could see LOG message abc.so library
loaded and I am able to call library methods at run time. But this requires
a client to connect to server and pass cmds. But I want a stand-alone
postgres server such that I can give commands directly from eclipse command
prompt itself. For that when I set the argument in run configuration as
"--single -D /home/rajmohan/projects/TPCH_database tpch",
the library loaded log message doesnot appears and library does not load.
How to load the library on stand-alone server and work?

Is it a custom extension that you are developing? Here you go:
http://www.postgresql.org/docs/devel/static/runtime-config-client.html#RUNTIME-CONFIG-CLIENT-PRELOAD
For an extension that needs to be loaded use shared_preload_libraries.
