How do I alter the position of a column in a PostgreSQL database table?

Question

I\'ve tried the following, but I was unsuccessful:

ALTER TABLE person ALTER COLUMN dob POSITION 37;

Answer 1

In PostgreSQL, while adding a field it would be added at the end of the table. If we need to insert into particular position then

alter table tablename rename to oldtable;
create table tablename (column defs go here);
insert into tablename (col1, col2, col3) select col1, col2, col3 from oldtable;
