I wish the documentation would include performance details, i.e. this operation is O(N) or O(1) relative to the number of rows.

I found renaming a table was okay.

How about renaming a column? Is it O(1) or proportional to the amount of data?

Is there any documentation about this?

https://www.postgresql.org/docs/10/static/sql-altertable.html

"RENAME

The RENAME forms change the name of a table (or an index, sequence, view, materialized view, or foreign table), the name of an individual column in a table, or the name of a constraint of the table. There is no effect on the stored data.

Thanks
