Postgres Database Patch

-
If you are used to patch Oracle databases you probably know how to use opatch to apply PSUs. How does PostgreSQL handle this? Do we need to patch the existing binaries to apply security fixes? The answer is: No.Lets say you want to patch PostgreSQL from version 10.5/11.3 to version 10.10/11.5. This is called minor version postgres upgrade or postgres patching Why need to patch postgresql server  ? Multiple SQL injection vulnerabilities have been discovered in PostgreSQL that could allow for arbitrary code execution. The vulnerabilities are the result of the application’s failure to sufficiently sanitize user-supplied input before using it in an SQL query. These vulnerabilities allow attackers with the CREATE permission (or Trigger permission in some tables) to exploit input sanitation vulnerabilities in the pg_upgrade and pg_dump functions. The CREATE permission is automatically given to new users on the public schema, and the public schema is the default schema used on the...

How to find the server is whether standby (slave) or primary(master) in Postgresql replication ?

-
Method 1 You can check the mode of the server using "pg_controldata". [pgsql@test~]$ pg_controldata /usr/local/pgsql/data84/ Database cluster state: in archive recovery --> This is Standby Database Database cluster state: in production --> This is Production Database [Master] Method 2 You can use pg_is_in_recovery() which returns True if recovery is still in progress(so the server is running in standby mode or slave) postgres=# select pg_is_in_recovery(); pg_is_in_recovery ------------------- t (1 row) If Return    false   so the server is running in primary mode or master postgres=# select pg_is_in_recovery(); pg_is_in_recovery ------------------- f (1 row)
