How to migrate transaction id to bigint

Prior to Aidbox release edge:2209 internal transactions table was using column with int type for tracking transaction id. This table is used behind the scenes for History API and ETags. In case of a heavy load updating this id can lead to integer overflow. Perform the following sequence of steps so that transaction id is accomodated with higher limit integer type.

• Truncate transactions table. This step is needed so that changing column type does not take a lot of time.

TRUNCATE transaction;

• Change column type.

ALTER TABLE transaction ALTER COLUMN id TYPE bigint;
ALTER SEQUENCE transaction_id_seq AS bigint;
