How big is the main SQL database where edits are saved to?
How big is the main SQL database containing nodes, ways and relations? I do not mean the planet file but the actual GIS database (PostGIS?) where the edits are saved to along with editing history etc. I know the [munin.openstreetmap.org][1] server stats site but I cant really get oriented there. I guess in the past the main db server was called [ramoth][2] but I am not sure if this is still the case. Looking at [ramoth's SQL size stats][3] the db seems to be about 6 TB in size as of today. Will anyone please confirm ramoth really is the main database server?
EDIT: It seems like ramoth is read-only mirror, the main server seems to be [katla][4] - however the its database size [database size][5] is the same of course.
