Depends on your operating system. Usually
/etc/init.d/postgresql start
You can see any errors in your logfile. Where is the logfile? Right,
depends on your OS and configuration.

You can use psql (the CLI for PostgreSQL), within:
test=*# show data_directory;
data_directory
------------------------------
/var/lib/postgresql/8.4/main
You need ALL the files below. You need also the same version of PG!
But that's the wrong way, the right way is a regular backup. See below!

Read the documentation, there are a chapter about backup and restore.
There are several ways, pg_dump, pg_dumpall (with diffent options) and
PITR (point in time recovery). Too much to explain all here...
Btw.: we don't have a 'repair' - command for tables. It's a feature, not
a bug ...
