Hello,
are there any plans of making Postgresql to properly support Unicode wrt
language-specific collations and upper/lower case handling?
AFAIK, currently the codepoints are sorted in their numerical order. I've
searched the source code and could not find the actual place where this is
done. I've seen executor/nodeSort.c and utils/tuplesort.c. AFAIU, they
are generic sorting routines.
Where is the actual code for (rudimentary) Unicode collation? Also, where
are the UPPER()/LOWER() functions being handled?
Thanks,
