Postgresql-9.6 backup










0















I have to backup a PostgreSQL database using this command:



sudo pg_dumpall -a mydb > app111618.bak



After I type that command, I get this error:



`pg_dumpall: too many command-line arguments (first is "mydb")`


In the command it say this:




Try pg_dumpall --help for more information.




How can I fix this?

          pg_dumpall is a tool to dump all databases, so it doesn't support specifying a database name (assuming that mydb is the name of the database you want to dump).



          If you want to dump only a single database, use pg_dump instead:



          pg_dump -a mydb > app111618.bak


          If you did intend to dump all databases, just leave out the database name:



          pg_dumpall -a > app111618.bak
