ALTER TABLE TYPE already rebuilds the indexes; you won't make the
overall process any faster by doi

Hi,
I wonder does ATER TABLE TYPE, SET, depends on indexes, like INSERT does
in a sense it may be faster to drop and recreate index than sorting
after every row inserted. Does changing type or setting default on an
indexed column require sorting?
Thanks, Zdravko

Hi,
I need to make some ALTER TABLEs. It takes about 30min to copy
this quite large databse, bat several ours to run a bunch of ALTER
TABLE statements.
Is there any way to make it faster? I wonder what could possibly alter
table be doing all this time.

When i alter a table and add a new column it always adds it to the end of the
table. Is there any way to tell it to add the new column at the 5th position or
to add the new column after a surtain column.

I think you need to alter columns one at a time. If you need them to
go into effect at the same time, you can wrap the multiple ALTER
TABLE statements in a transaction. For example,
begin;

TIP 8: exp
if the constraint are named $1 $2 etc you will need to quote them eg
ALTER TABLE xyz DROP CONSTRAINT "$1" ;
in some version you may require
ALTER TABLE xyz DROP CONSTRAINT "$1" RESTRICT;
What is ur version btw?
try to post the table structure also.

I think you can do some constraints in 7.2, but 7.3 will allow dropping
them all in that fashion.

I am attempting to add a few attributes to an existing table that already
contains data. The problem that I am having is that the new attributes
that I want to add need to be forgein key references to other tables. I
can't figure out how to create the attribute with a reference to another

How do I alter a table to set a column to be not null?
