Backup database through function in PostgreSQL

Question

Here i have sql server query to take backup of database using stored procedure as shown below:

Example:

 CREATE procedure DISKBACKUP  @location_dump varchar(255), @databasename varchar(255)                 
   AS                  
  backup Database @databasename to disk=@location_dump          
  ...

Can I do the same in PostgreSQL?

Answer 1

No, it is not.

pg_dump must be used.

It's often requested, but it's not supported at present, and nobody who requests it ever goes on to do any work to actually make it happen.
