Upgraded from Leopard to Snow Leopard - PostgreSQL won't start anymore - Mailing list pgsql-general

Hi,

some weeks or months ago I upgraded my Mac from Leopard to Snow Leopard.  Because I needed to work a long time remote I
didn'tuse my local dev system and found it broken now.  First of all I've got the following error message in my log: 

 FATAL:  could not create shared memory segment: Invalid argument
 DETAIL:  Failed system call was shmget(key=5432001, size=4374528, 03600).
 HINT:  [...]

After setting the value of shared_buffers from 2400kB to some lower (eg. 2000kB), the messages goes away but the
followingappears: 

 FATAL:  incorrect checksum in control file

I guess this is because I upgraded the OS without dumping the database before.  And now I'm stuck.  I found many pages
thatsuggests to make a pg_dumpall with the old database and the new pg_dumpall version.  But I (really) don't have the
oldsystem anymore and I guess it's impossible for me to get it from somewhere.  What can I do?  How can I dump the data
fromthe 32bit database?  Does someone has built a postgres binary for this issue? 

Thanks in advance,
 Matthias
