PgsqlMutex::acquireLock() should support $timeout with sleep()

[brandonkelly]

What steps will reproduce the problem?

1. Call yii\mutex\PgsqlMutex::acquireLock() passing in a non-null $timeout value.

What is the expected result?

The lock should wait up to the number of seconds defined by $timeout before giving up on acquiring the lock.

What do you get instead?

An InvalidArgumentException is thrown, because PostgreSQL doesn’t support lock timeouts like MySQL and Oracle do.

I realize that this is intended behavior so not exactly a bug, but why can’t PgsqlMutex just fall back on the sleep() function like FileMutex and yii\redis\Mutex do?

I think it can do so.

This is already fixed by #16839.
