If you want to go back to the old behavior, you can write -t “*.table_name”.Īlso, you must write something like -t schema_name.table_name to choose a table of a particular schema instead of the old options like -n schema_name -t table_name. Modern Postgres engines dump everything visible in your default search path. In old (before 8.2) PostgreSQL versions, -t table_name would dump all tables with the specified name.

It means that there is no guarantee that you will be able to restore this dump on a clean database without errors. In this case, pg_dump will not dump any other database objects linked to the selected table. To dump a single table, use the -t option: pg_dump -t table_name database_name > table.sql If your application does not reference the OID columns in any way, this option should not be used. If your database schema contains OIDs (like foreign keys), you must make pg_dump dumping the OIDs as well using the -o option. If you need to back up a remote server add -h and -p options: pg_dump -h host_name -p port_number database_name > database.sql The following commands will create a directory and add the record into the file in one batch: cd %appdata%Įcho localhost:5432: my_database:postgres: my_password > nf Backing up a remote server

Pg_dump -U postgres database_name > database.sqlĪs an alternative, when you don’t want to keep the password in a batch file, you can put the credentials to %APPDATA%\postgresql\nf in the following format: hostname:port:database:username:passwordĪsterisks can replace the hostname and database. You can do it by assigning a password to the PGPASSWORD variable: SET PGPASSWORD= my_password It will be useful if you run a backup in a batch or scripts where no user is present to enter a password. If you plan to back up a database automatically, then you might need to get rid of a password prompt. If your Windows user doesn’t have enough rights to your database then you can run this command from Postgres user: pg_dump -U postgres database_name > database.sql The command must be run by a user with privileges to read all of the database information.

The option for changing the environment variable is running the command with the full path, for example: “C:\Program Files\PostgreSQL\11\bin\pg_dump” database_name > database.sql If you got “pg_dump” is not recognized as an internal or external command” error add the path to PostgreSQL’s bin directory to the PATH environment variable (in my case it is “C:\Program Files\PostgreSQL\11\bin”). This command creates an SQL file containing commands necessary for recreating the database in the same state it was at the time of the backup. Or: pg_dump database_name -f database.sql The simplest usage of this command is: pg_dump database_name > database.sql Other backup methods, like file-level backups and continuous archiving, are bound to a particular server version and architecture. A crucial advantage of this utility is that you can restore its dumps on newer versions of PostgreSQL or on machines with different architectures.

#Dump table postgres dbvisualizer archive

In Postgres, to extract a database into a script file or other archive file, a utility called “ pg_dump” is used. Now let’s discuss these three methods one by one but if you prefer GUI tools you can use our free application to create database backups, which is, in essence, a powerful wrapper for pg_dump that creates SQL dumps.
