alter table to multi partitions

[Catalin Maftei <catalinmaftei@xxxxxxxxx>]

hello,

on a project I have large tables, with more than 2-5.000.000 rows, and the system is starting to be slow,

This tables have many dependencies functions, procedures and views.

I want to partition this tables. 

I think for this scenario for table Orders:
step1:     create new table with same structure ->  Orders_Part

step 2:    create all the partitions&triggers on new table Orders_Part
step 3:    copy/moved data from Orders to Orders_Part
step 4:    rename Orders to Orders_Old

If i want to drop Orders, it's necessary to drop all dependencies (and that's not what I want)
step 5:    rename Orders_Part to Orders

here is the problem - when rename Orders to Orders_old, postgres automatically change Orders to Orders_old in all dependencies (views, functions, sp) 

is there any postgres setting I can use to not  automatically change the in all the depandencies?
