Nope.

Exactly. This implies versioning support. One idea is to
even have all versions in one DB and create a release by
means of a suitable select/view.

Well, I think that about 1.5G are enough, the base in
question is about 700M or 3.5Mio games. Searching via flags
is very fast, searching by player names etc is very fast.
Searching by additional header tags is slow as they are not
indexed.

No, no, actually I'd like to place the CentriScid-ID as one
PGN Header tag. I suggested to set for a game in question
[CmailGameName "CentriScid:12-123456"]
(CmailGameName just as it is already used for a UID, but
this is up to discussion.)
I'd just prefer to add just _one_ line there and not
several. This eases up entry among other features (see
below). I'd prefer to have a generic ID-field and not a
specific one, as this could be indexed. E.g. if you name it
"CentriScidID" it is only usable in CentriScid as otherwise
it is not unique anymore. Therefore the DB-name that it
refers to has to be part of the ID. If you drop the version
from the UID you can not handle versioning with it anymore,
IMHO this is desirable. And well, one unique number has to
be there.
