Re: Removing a corrupt database by hand

I get this:

And it stays there forever..  I'm mucking around with stuff in the debugger right now and it's looking like it's crashing due to bad file handles..  In fact, this line might be the culprit:

SysLoggerPID = SysLogger_Start();

If I skip over it, it continues but then gets other errors due to bad file handles..  Heh, whatever I did totally wrecked the DB..  We really need some sort of dbrepair tool one of these days..

I have two questions actually..

First off, is there a way to remove a database if the postgres.exe 
service won't start?  It seems if I just delete the data\base\xxxxx 
directory, then postgres will crash.  Is there a way to drop a DB that 
prevents postgres.exe from starting?

    

What happens if you start postgresql in single user mode?

  

Second question, if I just re-install postgres and create a fresh new 
instance, is there a way to import my old data files back into the 
database?  Thanks!
