Actually it works on raw table file ;)

I attach code that dumps data from page file for table of 4 ints all NOT
NULL, like

create table fourints(
  i1 int not null,
  i2 int not null,
  i3 int not null,
  i4 int not null
);

the script is meant for quick and dirty resque operations, and requires
that one writes their own data-field extractor code. I have used it
mainly to resurrect accidentally deleted data.

it is for 7.x style pagefile layout
