in psql:

/copy (select * from table WHERE condition ) to 'FILENAME'

requires postgres version >= 8.2 IIRC.

you can use any query.

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

Thanks

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.

        Use copy command as follows if the OS is Linux,

postgres=# copy (select * from test where setid>20) to '/var/tmp/t2.dmp';
COPY 3
postgres=# \q
-bash-3.1$ cat /var/tmp/t2.dmp
1234    22      1       2009-01-08 00:00:00     dup1-2
9876    21      1       2009-01-10 00:00:00     dup2-1
1       21      1       2009-01-10 00:00:00     dup2-1
 
If it is Windows, use can use as,

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