If your concern is speed, the thing here is that you will have as many records
as there are in mytable, most of them (I think) with NULLs for alias1, alias2,

postgreSQL will do a sequential scan over the whole table.

Hi, I am not sure if this went through the first time so here it is again.

How 'bout these:

Hi,
I have a table messages which has (for simplicity) two columns -
msg_id, last_id, where last_id is sort of symbolical link -
it points to the msg_id of the last version of message.
There are no limitation to the number of versions.
The problem I have is to get history of message with given
301 - 400 of 417 matches
