Postgres Backup

Add postgresql repos to apt sources, if you use ubuntu do like that:

sudo sh -c 'echo "deb http://apt.postgresql.org/pub/repos/apt $(lsb_release -cs)-pgdg main" > /etc/apt/sources.list.d/pgdg.list'
wget -qO- https://www.postgresql.org/media/keys/ACCC4CF8.asc | sudo tee /etc/apt/trusted.gpg.d/pgdg.asc &>/dev/null

After that run sudo apt update and install postgresql-client, replace 15 with your postgresql version:

sudo apt install postgresql-client-15 -y

Backup

Add -Fc option to restore with pg_restore, it will create a custom format dump file and we can use with pg_restore.

pg_dump -h postgresql -p 5432 -U postgres --dbname=mydb -Fc --file="mydb-dump.dmp"

Restore

pg_restore -h postgresql -p 5432 -U postgres --dbname=sonar ./mydb-dump.dmp
