Forum OpenACS Q&A: Response to OpenACS.org mentioned in sidebar to Postgres Article in Linux Journal
I was also amazed to see an article about a database other than MySQL in LinuxJournal. I should note, however, that the Postgres article comes after a MySQL article.
One of the interesting things about the (good) article is that the author likes MySQL a lot, and pointed one the PG's limitations (not allowing UNIONs in VIEWS) like this:
"Other issues, such as the combination of views with unions, bit me (and my clients) on a recent programming project."
However, he did not mention that MySQL does not even HAVE views (the whole tone of the article is comparing PG and MySQL).
Another point that I can't comment on but would love to hear a more informed comment:
"The most pressing issue is probably the 8 KB limitation on each tuple or database row. This means that no row can contain more that 8 KB of data. This affects many parts of the database's operation, from providing only moderate support to BLOBs to preventing developers from creating even moderate-sized tables."
