Add single table load progress column to table statistics tab

It would be useful while full load is running to see in "Table Statistics" tab each table estimated progress in percentage ([target loaded rows]/[source_table_row_count]*100) based on the source table row count returning from this query on the source DB:

SQL Server:

SELECT SUM(row_count) AS source_table_row_count FROM sys.dm_db_partition_stats WHERE OBJECT_NAME(object_id)='table name' and index_id < 2 GROUP BY OBJECT_NAME(object_id);

Oracle:

SELECT num_rows AS source_table_row_count from all_tables where owner='schema name' and table_name='table name'

MySQL:

select table_rows AS source_table_row_count from information_schema.tables where table_schema='schema name' and table_name='table name'

PostgreSQL:

SELECT c.reltuples::bigint AS AS source_table_row_count FROM pg_class c JOIN pg_namespace n ON n.oid = c.relnamespace where n.nspname='schema name' and c.relname='table name' order by 1,2 ;
