Looks like Postgresql older than 7.x (7.3?)
You can't drop column this way. In older versions you can do this only by:
create table temp (columns as you wish to have)
insert into temp select * from old_table
drop old_table
alter table temp rename to old_table

I think you are using an old version of PostgreSQL. AFAIR this
functionality was implemented on 7.3. Here is mine:
*******************************************
postgres@[local]:test=# SELECT version();
version
- ---------------------------------------------------------------------------------------------------------
PostgreSQL 7.3.4 on i686-pc-linux-gnu, compiled by GCC gcc (GCC) 3.2.2
20030222 (Red Hat Linux 3.2.2-5)
(1 row)
postgres@[local]:test=# ALTER TABLE institution drop column name;
ALTER TABLE
*******************************************
Maybe you should upgrade your PostgreSQL.
