I'm trying to run psql on Windows 2000, but it prints an error message saying:
psql: could not create socket: An address incompatible with the requested protocol was used. (0x0000273F)
Debugging a small application I have written myself, I have discovered that the function 'socket()' inside the database connection function fails with the error: "The specified address family is not supported".
From the cygwin environment, psql is running fine, and I have properly installed cygipc.
