Using lock and fetch throws "No value specified for parameter 7" sql exception

See original GitHub issue

Hey @kagkarlsson!

Hope you’re well - using your fantastic library at my new place and I saw that version 10.0 includes the pollUsingLockAndFetch so wanted to test it out.

Anyway, end up getting a weird exception only in production:

Here’s my config:

        Scheduler
                .create(configureDataSource(dataSource))
                .tableName(TABLE_NAME)
                .pollingInterval(Duration.ofMillis(50))
                .heartbeatInterval(Duration.ofSeconds(30))
                .shutdownMaxWait(Duration.ofMinutes(1))
                .threads(THREADS)
                .executorService(executor)
                .startTasks(toTasks(jobs))
                .pollUsingLockAndFetch(0.5, 1.0)
                .build();

build.gradle

    implementation 'com.github.kagkarlsson:db-scheduler:10.0'
    implementation 'org.postgresql:postgresql:42.2.19'

I’m running postgres version 12.5 on AWS RDS.

From the stacktrace it seems to be throwing an error here: https://github.com/kagkarlsson/db-scheduler/blob/1d9139c42397562dd5c4cd793363eabdc84f762e/db-scheduler/src/main/java/com/github/kagkarlsson/scheduler/jdbc/PostgreSqlJdbcCustomization.java#L47-L70

I re-read the query a few times and as far as I can tell there seems to be six params there so I’m not sure sure where postgres is getting the 7th param from?

Anyway - would be great to get it working so let me know if you need anything else from my side!
