pg_dumpall:tldr:b4bb9
The command pg_dumpall
is a PostgreSQL utility that is used to create a plain-text dump of all the databases.
The --username=${username}
flag specifies the username to be used for the database connection. ${username}
is a placeholder that should be replaced with the actual username.
The > ${filename-sql}
part is used for output redirection. It redirects the output of the pg_dumpall
command to a file specified by ${filename-sql}
. ${filename-sql}
is another placeholder that should be replaced with the desired filename. The .sql
extension is commonly used for SQL dump files.
So, when executing this command with the appropriate values substituted for ${username}
and ${filename-sql}
, it will create a SQL dump of all the databases, using the specified username for the connection, and save it to the specified file.
