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't use 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 following appears: 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 that suggests to make a pg_dumpall with the old database and the new pg_dumpall version. But I (really) don't have the old system anymore and I guess it's impossible for me to get it from somewhere. What can I do? How can I dump the data from the 32bit database? Does someone has built a postgres binary for this issue?
