Re: type of a field

Short answer: You can't
Long answer: There are many workarounds.

Workaround 1:
dump the table with pg_dump dbase -t tablename
edit dump file to change table definition
drop and reload table.

Workaround 2:
Let's say you wanna change a varchar to a text type.

Original table t1:
col | type
----------
nam | varchar(32)
id | int4

select nam::text, id into t2 from t1;
drop table t1;
alter table t2 rename to t1;

You can do the above in a transaction if you are on a live database. I'd
back up the data first just to be sure.
