I am new to Postgres database. I have to get the backup from Production Server (pgAdmin Version is 9.2.4) & restore it on my local machine (I have pgAdmin Version 9.4). I tried to get backup by right clicking on database -> Backup to get the .backup file. Like shown in below image:
But when I try to restore the backup file, I get many errors.
I also want to know whether having different ports at both system can also create issues while restoring backups. As When I tried to restore backup of same system had no problems.
To backup a database you can use pg_dump.exe
:
Open Powershell
Go to Postgres bin folder. For example:
cd "C:\\Program Files\\PostgreSQL\\9.6\\bin"
Enter the command to dump your database. For example:
./pg_dump.exe -U postgres -d my_database_name -f D:\\Backup\\<backup-file-name>.sql
Type password for your postgres user
To restore a database you can use psql.exe
. (Note, the following is extracted from Alexandr Omelchenko's helpful answer which has been deleted for reasons not clear to me.)
Open Powershell
Go to Postgres bin folder. For example:
cd "C:\\ProgramFiles\\PostgreSQL\\9.6\\bin"
Enter the command to restore your database. For example:
./psql.exe -U postgres -d my_database_name -f D:\\Backup\\<backup-file-name>.sql
Type password for your postgres user
I was stuck here when creating the database dump file due to version mismatch. So I follow the below command to get the backup and restore.
pg_dump -h localhost -U postgres -p 5432 YourDbName > BackupFileName.dump
As an alternative, you can try below cmd code. If you trouble with restoring from pgAdmin4, you can try this. First you should find the path pg_restore.exe. It is generally in
C:\\Program Files\\PostgreSQL\\12\\bin>
run the below code after changing database name and backup path
pg_restore.exe --verbose --clean -U "postgres" --dbname databaseName c:\database.backup
