Viewing table data only from its corresponding oid-named file

<small><font face="Courier New, Courier, monospace">Hi Guys<br /><br /> I have some files that were part of a database,
Imean they were under /<b>data/base/DB_OID/table_oid</b> postgres structure<br /><br /> As I understand <b>table_oid
</b>whichis a numbered file corresponds to one table in the original database.<br /><br /> Here is my question: Is
therea tool/method to view the data in this file so I can get a clue of what the data in that table was?<br /><br /> We
hada major drive crash and we could recover only a few of those files and want to know if we have a chance to recover
somedata only from those kind of files.<br /><br /> Thanks in advance.<br /><br /> --<br /> Heiner
