Sorry, your presumption is wrong. In contrary to what the name might 
suggest this file is not a log file at all. 
Your dbase is probably seriously damaged. 
If you haven't made a dbase dump using "pg_dump" before, 
you'd better do that full rebuild you mentioned.

PS I recommend to read the chapter 'Backup and Restore' of the 
fine manual to be prepared when your machine crashes again.
