Re: postgresql data transfer from 9.3 to 9.4 - Mailing list pgsql-bugs

Dear Support Team,We face a question about migrating postgresql from 9.3 to 9.4. Because our original postgresql is 9.3. And we use dump command to dump all record as shown as below:pg_dump dbname > outfileAt the same time , we update postgresql from 9.3 to .9.4 And then remove 9.3 postgresql. Finally we use command as listed as below to import all record to 9.4 postgresql.psql dbname < infileBut at the transfer process, it showed the error message as shown as the attachment. How can we normally transfer 9.3 records to 9.4 postgresql in the same server? Thanks for your kindly assistance.Best Regards, Anderson Hsu
1. You should to use dump from target version, not from original. There is not problem to have more installed version of postgresql client software (pg_dump and other).
2. what you see is last error, you should to show first error
run:
psql -v ON_ERROR_STOP=1 dbname < infile
psql -v ON_ERROR_STOP=1 dbname < infile
3. removing original release before successful migration is wrong
4. for these versions, you can migrate by faster pg_upgrade command
