postgres console delete mistake

hello
I accidentally deleted every recordes from my table
whithout a back up for my data such as pg_dump.
How can I restore
them?
I found that deleted data are alrealy in my databes
files such as /var/lib/pgsql/data/base/*
and transactions are loged in
/var/lib/pgsql/data/pg_xlog/00000001,000000002
but the file formats are not alrealy readable for me.
I found a tool pg_filedump but I'm not found it usable
for this problem.
Is there a tool for data recovery in postgres.
