Alter table

I am looking for the SQL query to add a column in a table and having the column at specific position in the table (not at the end of the table).
 
Do you have any idea ?

I think that's a TODO item (i.e. it's not implemented yet.)

Currently you'd have to either pg_dump and rearrange your data, or
recreate the table with a select into / insert from select type thing.

select field1, field2, field4, ''::text as newfield, field3 into newtable
from oldtable;

Sorry - you'll need to dump and restore the table. PG only adds columns at the
end.
