PostreSQL doesn't track this kind of thing for you. An easy method to
implement yourself is to create a table to track such changes, and add
a line to insert data into that table.
create table change_track (version numeric(12,2) primary key, title
text, summary text);
Then in a script, always update like so:
begin;
insert into change_track(10.2, 'plpgsql - add / remove','New plpgsql
stored procedure to add and remove users. adduser(uid,''username''),
deluser(uid)');
create function....
commit;
That way, if some part of the update fails it all fails and you don't
have any of it in your db.
Then you can just check change_track to see what stuff is in your db.
Plus you can check the scripts into svn for management.
