Reading the contents of the file will give you the answer... :-) Looks like you got an error message instead of a dump.
Also, I'd guess from the above that you used PhpPgAdmin, not pgAdmin; they're two very different animals.

You are right I got an error message instead of data but yesterday i got a text file which contained database information I dont know today the text file looked like this. And am using phppgadmin.
