使用带有JOOQ的Timescale DB的Gapfill引发参数：start不能为NULL

Question

我正在运行一个Timescale数据库，并且正在使用JOOQ访问数据。

我正在将gapfill()用于

dslContext
        .select(Routines.timeBucketGapfill5(
                Routines.createInterval(DURATION), table.TIME, null, null).as(FieldName.TIME_BUCKET),
                ifnull(count(table.STATUS), 0).as(FieldName.STATUS))
        .from(table)
        .where(table.ID.in(ids)
                .and(table.TIME.ge(Timestamp.from(Instant.now().minus(Duration.ofSeconds(DURATION)))))
                .and(table.TIME.le(Timestamp.from(Instant.now())))
                .and(table.STATUS.eq(status)))
        .groupBy(field(FieldName.TIME_BUCKET))
        .fetch()

有时我得到一个

org.postgresql.util.PSQLException: ERROR: invalid time_bucket_gapfill argument: start cannot be NULL
  Hinweis: You can either pass start and finish as arguments or in the WHERE clause

如果我总是有一个带有equalsEquals和lessEquals的where子句，start如何为NULL？

我能够记录SQL语句。如果我直接在数据库上运行该查询，它将正常工作。

select "public"."time_bucket_gapfill"("bucket_width" := cast("public"."create_interval"("seconds" := 43200) as "pg_catalog"."interval"), "ts" := cast("public"."device_health"."time" as timestamp), "start" := cast(null as timestamp), "finish" := cast(null as timestamp)) as "time_bucket", coalesce(count("public"."device_health"."health"), 0) as "health" from "public"."device_health" where ("public"."device_health"."device" in ('700004', '700009', '700008', '700005', '700007', '700000', '700003', '700001', '700002', '700006') and "public"."device_health"."time" >= timestamp '2020-03-11 13:59:20.0564238' and "public"."device_health"."time" <= timestamp '2020-03-25 13:59:20.0564238' and "public"."device_health"."health" = 'OK') group by time_bucket

如果在gapfill调用中传递与start和finish可选参数相同的参数，是否会看到相同的错误？您是否能够捕获JOOQ正在合成的实际SQL？
