I tried using /copy command. It is not giving any error but also not creating any file.

It should be \copy . This is a psql command; if you have direct access to database host machine, you might want to use the SQL command COPY for it's performance.

in psql:
/copy (select * from table WHERE condition ) to 'FILENAME'
requires postgres version >= 8.2 IIRC.
you can use any query.

postgres=# copy (select *from test where a<6) to 'C:/Program Files/PostgreSQL/8.3/data/samp.sql';
COPY 9
