Hello Jon, It would be very useful to add how to save video at the beginning. I found a work around, I used every time I logged into PGAdmin, but my work around doesn't work with cloning. I get the error message "there are two other sessions using this database". Alternatively, It would be nice to get a resources package, if we don't manage to clone. BTW I like your SQL course a lot, I recommend everyone to check it.

Thanks for this crystal clear explanation... The syntax for using both WHERE and HAVING clauses could have been SELECT AGG(Column_name1), Column_name2 from table_name WHERE column_name3 = value1 GROUP BY Column_name2 HAVING AGG(Column_name1) > value2
