Pretty straightforward. Had some concerns about locking, but due to the fact that all distributed operations use either some level of deparsing or need to enumerate column names, they all block during any concurrent column renames (due to the AccessExclusive lock). In addition, I had some misgivings about permitting renames of the dis- tribution column, but nothing bad comes from just allowing them. Finally, I tried to trigger any sort of error using prepared statements and could not trigger any errors not also exhibited by plain PostgreSQL tables. |
