Forum OpenACS Q&A: Re: PostgreSQL MVCC transaction model

Posted by Andrew Piskorski on
Ah, according to page 12 of Tom Lane's PDF slides from 2000, when in read commited isolation level (the default) an update may be allowed to see rows committed by other transactions after the update started, but a pure select transaction will never see such rows. Is that what that sentence from the docs above was trying to say, and got confused somehow?
