Why schema-on-demand? Can you explain what you mean by that?
Something that is attractive, for beginners or perhaps when prototyping is
that you don't have to declare a table. You c
Absolutely not. SQL is a (nearly) full implementation of the relational
algebra, plus other non-relational stuff. The only thing it really can't handle
is a table with no columns! (I have to fake that)
a table with no columns would have no primary key... doesn't that violate one

Hello,
There was a corruption to the file system due to sudden shutdown of Windows
7.
The attempt to connect to one of the databases results in multiple errors,
like the following one:
ERROR: invalid page in block 58 of relation base/161326/233745
Several raw files were completely lost (zeroed)

This is precisely what I mean by wonky semantics: it makes no sense
for a nullary relation to be interpreted as selecting a NULL. A ro

Thank you. I didn't know that.
