pg_stat_progress_data_checksums uses -1 as a sentinel value that is displayed as NULL for progress counters. However, after pgstat_progress_start_command() initialized all progress counters to zero, data checksum progress did not reset those counters to -1. As a result, some counters could incorrectly appear as zero instead of NULL. For example, workers could report zero database counters, and the disabling launcher could report zero relation and block counters. Also, blocks_done was not reset when a worker started processing a new relation fork. As a result, it could temporarily exceed blocks_total or report a stale value for an empty relation fork. Fix this by initializing the data checksum progress counters to -1 when progress reporting starts for both launcher and worker processes. Also reset blocks_done together with blocks_total when starting each relation fork.
