Description

Martin may become unresponsive while PostgreSQL is handling a lot of long-running SQL queries. Some frontends like Nginx may also cancel requests based on timeout, but these requests might still be running as queries in PostgreSQL.

We need a way to set a timeout for such requests, so we can cancel queries in the PostgreSQL.

Contributor guide

Research direction
Explore PostgreSQL's statement timeout and libpq's cancel query methods, then implement configurable timeout in Martin.
