Error after typing "psql"

Hi!!
I just installed PostgreSQL in a MSW98 using cygwin. When I type 'psql' I get a message saying
psql: could not connect to server: No such file or directory
        Is the server running locally and accepting connections on Unix domain socket "/tmp/.s.PGSQL.5432
What can I do to solve this problem?
