New Post: Accessing psql after login to a server

I was able to successfully connect to a server using SSH in C#.
the server has Postgres client listed as one of its applications.
The problem is, if I enter the command "psql" in putty, it would take me to the interactive client.
however, if I try to do it in code,
runCommand("psql"); and write the result to console.
nothing happens.

Any help would be appreciated.
