Instead of that, I think it would be more foolproof to do

CREATE PARTITION ON parent_table FOR ( value1, ... );

instead of trusting the user to get the exact start value correct.

Though... I guess there could be value in allowing an exact start value 
but throwing an error if it doesn't sit exactly on a boundary. Might 
make it less likely to accidentally create the wrong partition.
