I have a question of how we can restore a local database backup in Azure PostgreSQL server?
Make sure you can access your database from the computer you are restoring the DB dump
pg_restore --dbname=postgresql://user:password#host:port/database_name ./path/to/your/dump.tar.gz

I have just signed up to Heroku basic-hobby and created a PostgreSQL DB. I have a DB that I wish to restore. How do I upload the DB and where do I access the functionality to restore?
I found where to create a manual backup but nowhere how to do a restore.
I'm learning some backend stuff, I made a test database locally and filled some data, and then I dump the database to an SQL file with the following command:
pg_dump -U USERNAME DATABASE —no-owner —no-acl -f backup.sql
And finally restore it to Heroku:
heroku pg:psql —app APPNAME < backup.sql
There is only 1 database I’m deploying, however, when I use PGAdmin to connect to it, it shows more than 2000 databases and crashes my computer:
Where are all these databases coming from?
You don't get a dedicated PostgreSQL server with Heroku Postgres. Your databases are co-located with other users' databases on the same server. You'll be able to see the names of other users' databases, but you won't be able to access them.
I'm not sure what "crashes my computer" means, but make sure you are selecting your database when trying to connect.
We have the database named 'itreport' on production server and database named 'itreport_dev' on development server.
1)On Production server, 52 users are present in the database 'itreport'.
2)On Development server, 60 users are in present the database 'itreport_dev'.
3)I have taken the dump of production server database 'itreport'. Dump file name is backup_12082017.sql
My question is
If I restore the above dump(backup) file to Development server database 'itreport_dev, Users(60) present will present in the Development database?
If not what option we have to give in the restore process?
What are the pre steps and post steps to be performed on Develpement server?
Short answer: No, roles are not part of a single-database backup.
If you dump only the database using pg_dump it will only restore tables and data. not any roles. any objects owned by missing roles will end up owned by the user performing the restore (this user should be a superuser)
If you do pg_dumpall roles and all databases will be backed up.
Roles can be backed up separately using pg_dumpall -r
if you do pgdumpall --clean the resore will destroy and replace any databases and roles on the dev server that also exist in the dump. any names that are not in both will be unaffected, (the special role "postgres" and template databases also are untouched)
pgdumpall backups are SQL backups and should be restores using psql
su postgres -c psql < all-database-backupfile.sql
or
zcat all-database-backupfile.sql.gz | su postgres -c psql
etc.
(for windows use runas instead of su, I'm not sure of the exact syntax needed)
Setup --
I have a postgresql db running on AWS RDS. We access it from an EC2 instance using pgAdmin 3.
Current Scenario --
AWS takes a daily backup of the entire RDS instance as RDS snapshots which is stored for 15 days.
I take a manual backup of one important schema (all the data in schema included) using pgAdmin and then push this backup file to s3.
Question --
How do I automate this backup of a single schema (including data) in postgresql and store it on S3 (any application or script). Is there a way to automate it in pgadmin just for one schema and not the entire database.
You need to use a command line tool pg_dump:
pg_dump \
--host=myhostname.qwertyuiop.sc-moon-1.rds.amazonaws.com \
--username=myusername --dbname=mydbname \
--format=custom --file=mydbname.pg_dump
It needs to be the same major version as the database.
I have restored a snapshot from an existing RDS PostgreSQL database. Now I want to rename that database but can't find how to do it anywhere in the AWS documentation.
Nor can I find how to use the master password (which I expect let's me do it).
Logging in with postgres into template1 database and then ALTER DATABASE foo RENAME TO bar; worked
