Обсуждение: Transferring DATA directory
Hi,
I'm trying to transfer large amounts of data between two PostgreSQL 8.1.2 database Windows XP platforms using the physical filesystem backup method. I used the same PostgreSQL installer on both machines and the same PostgreSQL configuration. I also used default options with PostGIS options. I did the following:
1. shut down the database on each of machine A and machine B,
2. zipped up the <postgre-home>\DATA directory on machine A and unzipped it onto machine B.
3. when I started up PostgreSQL on machine B with machine A's data directory, the following message is returned:
"The PostgreSQL Database Server 8.1 service could not be started.
The service did not report an error.
More help is available by typing NET HELPMSG 3534"
I'm trying not to transfer data using pg_dump as it's quite a lot of data and highly time consuming. Does anyone know if this is possible. I've verified that there is no .pid file in the DATA directory. Are there other files I am missing? Anything else I might try?
Thanks,
Alfred Lau
