I can't see this information being useful to our general users. > - 9da86753 - Reject duplicate column names in foreign key referenced-columns > lists. > behavioural change, should be documented as intentional Uh, well, I didn't think such uses were common, and we now issue a very clear error message, so I didn't think it was worth mentioning. > - 680513ab - Break out OpenSSL-specific code to separate files. > should perhaps be mentioned in the developer section.

Uh, again, not really for the group of developers I usually worry about in the release notes. > - 94028691 - Advance backend's advertised xmin more aggressively. > Pretty good feature imo. Yeah, but again, do our general users understand enough to even understand the explaination, and even if they do, do they care. > - 5028f22f6 - Switch to CRC-32C in WAL and other places. > This might have compability impact in some external tools. Agreed, text updated: Speed up <acronym>CRC</> (cyclic redundancy check) computations and switch to CRC-32C (Abhijit Menon-Sen, Heikki Linnakangas) > - 4f1b890b1 - > Unsure if this should be mentioned, at least it's a fairly > large change. This is: Merge the various forms of transaction commit & abort records. Again, much too internal-focused for our users to care. > - 27846f02 - Optimize locking a tuple already locked by another subxact > Several users ran into this slowness, so I think we should mention the > optimization. I usually don't mention speedup of edge cases. There are problably a few people who care about it though, but this will be read by thousands of people. -- Bruce Momjian <br...@momjian.us> http://momjian.us EnterpriseDB http://enterprisedb.com + Everyone has their own god. + -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
