Re: Stopping writes in master - Mailing list pgsql-admin
Thanks Shreeyansh.
Can this be handled from the server side may be setting some config parameters and then restarting the master so that existing connections gets dropped and the new ones not able to write?

Hi Debraj Manna,
Yes,You can make the database read only as well just by setting the below parameter is equal to true at the session level.But you need reconnect your existing connections.ALTER DATABASE YOUR_DATABASE_NAME SET default_transaction_read_only = true;

are you trying to switch the database to a read-only mode for backup purposes or
