Is it possibly to specify Postgres column storage type at table creation?

Can one specify the EXTENDED storage type for a column as part开发者_如何学运维 of CREATE TABLE? If yes, would it also work under Postgres 8.1?

I don't see a way to do this except through ALTER TABLE, which seems weird for something that really belongs with the rest of the table definition.

I don' think you can.

"Each TOAST-able data type specifies a default strategy for columns of that data type, but the strategy for a given table column can be altered with ALTER TABLE SET STORAGE."
