Обсуждение: Backup complete

Dear all,

I take backup of postgres databases with pg_dump command.
But it didn't take backup of all sequences,views & functions in
different databases.

I want to know how we can complete backup so we can get complete data
after restoring from a single file.

I faced errors when dumping data from one system to another , if the
same sequence doesn't exist in the other system.


Thanks

That's because you told it to backup only the postgres database. pg_dump
only dumps a single database. If you want to backup all databases in the
cluster, use pg_dumpall.

You should read up on the two commands in the documentation:

Check out pg_dumpall:

Hi Adarsh,

Yes, pg_dump backs up everything - schema and data. If you need to
convince yourself, use the -s option to dump just the schema and examine
the output.
