Recovering a table

Hi

I just broke my pgsql system a bit. One database doesn't show any tables
for a database when using psql but the file containing the data in the
pgsql homedir still exists at /var/lib/postgres/data/base/<db>/<table> . Is
there a way to just 'tell' the backend about the file or maybe import the
file?

Thanks
