Would existing constraints and indexes applied to an old table, apply to a new table renamed like the old one after it's dropped? everything is in the question.

I have a table named tableA on which we have indexes and foreign keys and constraints.

I have to modify content in a column called column1. This being a production system, I want to 

1) create a copy of tableA called tableA_temp
2) Perform the data change (some concatenation and regexp_replace)
3) Obtain validation that the change is correct
4) rename tableA to tableA_old
4) Rename tableA_temp to tableA.


Once renamed to tableA, would the constraints and indexes apply to the new tableA?

My guess is yes but I would need a little validation.
No. 

Ok, it depends on if you create them on the copy.
