# the other workers don't select it too.

# future and the optional triggers are removed.

# again quickly (e.g. high frequency or self-triggering cron).

# This function doesn't prevent from acquiring that job multiple
|

|
# times at different moments. This can block a worker on
|
||
|
|
# executing a same job in loop. To prevent this problem, the
|
||

# callee is responsible of providing a `job_ids` tuple without
|
||
|
|
# the jobs it has executed already.

# An `UPDATE` lock type is the strongest row lock, it conflicts
|

|
|
# with ALL other lock types. Among them the `KEY SHARE` row lock

|
|
# which is implicitely aquired by foreign keys to prevent the
