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

I’ve tried the following, but I was unsuccessful:

ALTER TABLE person ALTER COLUMN dob POSITION 37;

Answer

“Alter column position” in the PostgreSQL Wiki says:

PostgreSQL currently defines column order based on the attnum column of the pg_attribute table. The only way to change column order is either by recreating the table, or by adding columns and rotating data until you reach the desired layout.

That’s pretty weak, but in their defense, in standard SQL, there is no solution for repositioning a column either. Database brands that support changing the ordinal position of a column are defining an extension to SQL syntax.

One other idea occurs to me: you can define a VIEW that specifies the order of columns how you like it, without changing the physical position of the column in the base table.
