pg_restore: error: too many command-line arguments
The “pg_restore: error: too many command-line arguments” error occurs when you provide too many arguments to the pg_restore
command. The pg_restore
command is used to restore a PostgreSQL database from a backup file created by pg_dump
or pg_dumpall
.
To fix this error, you need to ensure that the command is properly formatted with the correct arguments. The basic syntax of the pg_restore
command is as follows:
pg_restore [options] [path/to/backup/file]
Here, the [options]
are optional arguments that modify the behavior of the command, and the [path/to/backup/file]
is the path to the backup file you want to restore. If you provide additional arguments after the backup file path, the “too many command-line arguments” error will occur.
Examples:
Let’s consider a few examples to illustrate this issue:
-
pg_restore -U username -d dbname backup.dump additional-argument
In this example, the
additional-argument
is unnecessary and causes the error. To fix it, you should remove the unnecessary argument:pg_restore -U username -d dbname backup.dump
-
pg_restore -U username -d dbname backup.dump -C --if-exists
Here, the
-C
and--if-exists
are valid options, but they should not be included after the backup file path. To resolve the error, you need to place these options before the backup file:pg_restore -U username -d dbname -C --if-exists backup.dump
By ensuring that the command is properly formatted without any unnecessary arguments, you should be able to resolve the “pg_restore: error: too many command-line arguments” issue.
