Andrew,
I would like also to see full collation implementation rather then collation per
database. But from my point of view split collation into small parts is much
better. Radek's work is mostly about creating infrastructure for full collation
support. When it will be finished, then "only" changes in parser, executor...
will be necessary to complete a job.
If you look on most discussion about collation they fell into ICU yes/no problem
without any real decision how to implemented the feature.
