You can limit the amount of time that postgres will execute a statement
by setting a hard timeout. By default the timeout is 0 (see show statement_timeout;
) which means statements will be given as much time as
they need.
If you do want to limit your statements, to say, 1 second, you can set the execution time like so
> set statement_timeout = '1s';
SET
> show statement_timeout;
statement_timeout
-------------------
1s
(1 row)
Any queries taking longer than 1 second will be aborted with the following message output
ERROR: canceling statement due to statement timeout
