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 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 accidentally dropped original postgres database after installing postgreSQL software. Postgres user is still there, \du superuser. How to recover or recreate original postgres database?
https://www.postgresql.org/docs/current/static/sql-createdatabase.html
just run
create database postgres;
it will create db with default template (which is "template1"). If you did not modify it - it will be same is previous "postgres" db
You can only recover it if you have some previous backup of that database, by restoring that backup and then applying WAL files upto the time when drop database statement was issued.
There is no other way to recover a dropped database.
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
I'm having some trouble backing up and restoring a database in pgAdmin.
With pgAdmin, the backup is pretty simple.
If I try to restore the data to my live database, I get all kinds of foreign key errors and duplicate data. So the only way for me now is to drop all constraints, drop all tables and run the restore.
Is there a simpler way to restore a live database? My systems are not directly connected, I'm using file transfer to copy over the backed up db dump.
