Обсуждение: backup script
GM, First where can I post my question on the forum? Couldn't find the forum for discussion. Second, I'm new with postgres. Try to evaluate this new db software before the company can switch all oracle and mysql to postgres. I don't understand the concept how to create backup user, tablespace, etc.... Where can I create those from? Do I need to go to template1 and create them? This software has no much help online and confused me... please help Thanks, Bach-Nga Catherine Vo 703-767-7009 mailto: bvo.ctr@dtic.mil

Some of this happens in the database, some in the operating system. If you give details of your platform - hardware and software - people will be able to help you.

We are using Sun Solaris 64bits version 10. postgresql-9.1.3-S10.sparc-6 I downloaded the script from some of the website and try to test out but didn't work at all. Don't know how to create a backup user (I know the syntax but where should I create it?) Normall, we goes to sqlplus / as sysdba on oracle and mysql -u root -p on mysql, but where should I create it on postgres? Also, when I start the postgres, I saw 5 processes running... this is odd isn't it? Beside that, don't see port running on /tmp directory.

I don't know Solaris, but with the installation of Postgres on Linux there usually comes a user "postgres". That user is by default a superuser on the primary database called "postgres" and can connect to it without a password. So you could use that default superuser - or better create a new user for backups: http://www.postgresql.org/docs/9.1/static/sql-createuser.html http://www.postgresql.org/docs/9.1/static/app-createuser.html > Normall, we goes to sqlplus / as > sysdba on oracle and mysql -u root -p on mysql, but where should I > create it on postgres? > > Also, when I start the postgres, I saw 5 processes running... this is > odd isn't it?

I'll try to get you pointed in the right direction. The tools you need are called pg_dump and/or pg_dumpall: http://www.postgresql.org/docs/current/static/app-pgdump.html http://www.postgresql.org/docs/current/static/app-pg-dumpall.html The tools connect to the database pretty much like any other PostgreSQL client connects (user/password/dbname/etc.) and must have permissions appropriate to access the data being dumped. This does not necessarily need to be a superuser. If Pat owns his/her database and wants to dump it s/he can. To dump everything in the database cluster (user/role information, all databases, ...) requires superuser privilege. The PostgreSQL superuser is "postgres". For any connection to the database, whether general user or for doing dumps, you need to make sure the connection is allowed in pg_hba.conf: http://www.postgresql.org/docs/current/static/auth-pg-hba-conf.html > Also, when I start the postgres, I saw 5 processes running... this is > odd isn't it? Not odd at all. There is a main process listening for connections plus several helper processes doing things like managing statistics collection, managing database vacuuming (maintenance including dead-space reclamation through autovacuum) and so on. There will also be a process for every connected user. > Beside that, don't see port running on /tmp directory. > That is a default but can be changed a build-time or through configuration: http://www.postgresql.org/docs/current/static/runtime-config-connection.html If your database is running and you can connect, try: show unix_socket_directory; Cheers, Steve
Hi, So exactly what do I need to do here? I don't understand how the backup script work and what exactly user do I need to create? Can you please tell me more in detail?
