Nope.

Not sure what this means.

Not done.

I looked at that TODO.detail file, and it all seems to be ancient
history. Didn't we resolve those issues to peoples' satisfaction in 7.3?

I put in read-only variables for the things that seemed most interesting
(LC_COLLATE for example), but the coverage isn't complete.

AFAIK this is pretty much fixed.

Not done (unless this is referring to RETURN NEXT, but I think it's
talking about multiple output parameters).

Not done.

Done.

Not done.

Dunno what this is referring to.

Not done.
> * Add optional CRC checksum to heap and index pages
Not done.
> o Add optional textual message to NOTIFY
Not done, but there is room in the FE/BE protocol now for something like
this.
