Actually, I don't think this can be approved just by inspection. The DBI 1.43
changelog says:

"Fixed last_insert_id(...) thanks to Rudy Lippan."

We currently only require DBI 1.36. We have to see if bz_last_key actually
works properly on the version of DBI that we require.

Yes, in fact, here's the DBI 1.38 changelog:

"Added $dbh->last_insert_id method."

I don't get it... Shouldn't then get the patch on bug 237862 get the r-, and
this one r+?

Comment 6

[Max Kanat-Alexander]

Well... that's an interesting question. I'll address it in bug 237862. I think
you're probably right, though.

Ok, so is this r+ or r- from you? :-)

r-. See bug 237862. I've also discovered that only the cutting-edge version of
DBD::mysql supports last_insert_id, and only a development version of DBD::Pg
supports it. So at this point, we really shouldn't use it for our db compat
layer. :-)

Oh, nevermind! :-) Tomas has explained that bz_last_key does in fact work, and
it's overridden in the subclasses. :-)

V1.1, unbitrotted

r=mkanat by inspection and by assuring that there are no LAST_INSERT_ID
statements left after this.

Here goes nothing.

Someone better be prepared to hit landfill/bugzilla-tip an hour or two after
this lands and play with it like crazy :)
