rebuilding a table from a datafile

This is with regards to Postgres 6.5.

While trying to ALTER RENAME a large table (203MB data file), an error
occured. \d displays the new table name, but there is no corresponding
file.  a file with the original table name still exists, so presumably the
data is not lost. Is it possible for me to undo the RENAME by massaging the
pg_* tables, or otherwise retrieve the data in the table? It was an
insert-only table, and no deletes or updates were ever performed on it.

I'm smarter than average. Therefore, average, to me, seems kind of stupid.
People weren't purposely being stupid. It just came naturally.
