Обсуждение: grant on sequence and pg_restore/pg_dump problem
Hi, I did a quick search and didn't see anything on this, if I missed it sorry in advance. Anyway, I was doing a restore of a 8.1 database(on a 8.1 server) using the 8.2 pg_restore and it was throwing errors when it was trying to restore the permissions on the sequences. basically the pg_restore was using the grant on sequence against the 8.1 database which of course 8.1 knows nothing about. Is there a switch or something I missed that would allow this to work properly on a 8.1 or lower database? Or do I have to now have 2 versions of dump/restore in order to do this? Thanks, -- Tony

You can use 8.2 to dump 8.1, but for restore, you should use the same version as the target database. -- Bruce Momjian <bruce@momjian.us> http://momjian.us EnterpriseDB http://www.enterprisedb.com + If your life is a hard drive, Christ can be your backup. +

Wasn't the restore pretty much backwards compatible until now? Certainly pg_restore must know what version of the server it's connecting to, shouldn't it be able to adjust the GRANT ON so on versions < 8.2 it does not use the SEQUENCE keyword?

We have never spent time making restore work for all versions, partly because pg_dump typically dumps as text, and you just feed that into psql. -- Bruce Momjian <bruce@momjian.us> http://momjian.us EnterpriseDB http://www.enterprisedb.com + If your life is a hard drive, Christ can be your backup. +
