PostgreSQL is a popular open source relational database management system that is widely used for storing and managing data. Replication lag is the delay between the time when data is written to the primary database and the time when it is replicated to the standby databases. What is replication lag?

WAFs protect the network perimeter and monitor, filter, or block HTTP traffic. This also means we do not rely on vulnerability databases but are able to identify and block such attacks automatically even if they are exploiting unknown weaknesses.
