Hello SIr,
Please clarify about why $1 is not been replaced by 'colname' in delete_from_table2 function.

It has been replace with the string literal value ‘colname’, not a column reference identifier “colname”.  You cannot use positional parameters to supply identifiers.  Structure must be known at parse time.
