I've forwarded this request the to the OSM talk list. Hopefully someone who
can talk 'on the record' will step forward.

The master OSM database used for editing used to by MySQL but most of the
map rendering was done from Postgis hosted data. Over the weekend they
switched ,as part of an API upgrade, the main editing database
to Postgresql (but still not using complex geometry types).

I think the reasoning had to do with them wanting transactions and the
switch to InnoDB brought has some downsides, but I don't know which of the
innodb downsides motivated the switch.

I think the reference to MonetDB was part of an April fools joke.
