I'm assuming you've made a jump in database version - ie, 7.4 to 8.2 or
similar.

 

You need to use initdb to create new database files, then pg_dumpall on the
old system to dump the data out of the old before importing to the new. Make
sure you use pg_dumpall from the new version to dump the data from the old
database.

All,

 

I was hoping someone can help me fix a big blunder.  I recently bought a new
system to replace the old one.  The new system is running 64bit linux and
the old one 32bit.  I installed PG 64-bit and tried to bring the old
database back up.  Even though I'm running the same version of PG, it is
giving me an error when I try to start it back up.  below is the message
from pgstartup.log.  It looks like it doesn't recognize the control file
anymore.

 

Am I screwed?  I don't have the old system anymore and I didn't do a dump.
I figure if I'm running the same version of PG, the data will come back up
correctly.  If someone can help me out of this jam, I would greatly
appreciate it. 

 

Thanks,

David

The files belonging to this database system will be owned by user
"postgres".
This user must also own the server process.

The database cluster will be initialized with locale en_US.UTF-8.
The default database encoding has accordingly been set to UTF8.

Success. You can now start the database server using:
