What does the statement timeout mean in PostgreSQL?

edit

In PostgreSQL, timeout refers to the maximum amount of time that a process or operation can take before it is aborted or cancelled. When a timeout occurs, the process is forcibly terminated by the database system. This can happen when a SQL query or transaction takes longer to complete than the specified timeout setting, or when a client connection remains inactive for a certain period of time. The timeout setting can be adjusted in the PostgreSQL configuration file or using the SET statement in SQL queries.
