pg_restore problem

[Dinesh <dbhandary(at)mongonet(dot)net>]

Hi ALL,

I am trying to restore 2G dump file using pg_restore and it will erros 
out with the following message;
pg_restore: [custom archiver] could not uncompress data: too many length 
or distance symbol". Has anyone seen this before? I 'd really appreciate 
your help.

Thanks,

Dinesh
