So, does uloc_canonicalize() always convert to ICU locale IDs? What if
you pass a language tag, does it convert it to ICU locale ID as well?

0002 and 0003 look ok to me now.
In 0002, the error "opening default collator is not supported", should
that be an assert or an elog? Is it reachable by the user?
You might want to check the declarations at the top of pg_ucol_open().
0003 reformats them after they were just added in 0002. Maybe check
that they are pgindent'ed in 0002 properly.
I don't understand patch 0004. It seems to do two things, handle
C/POSIX locale specifications and add an SQL-callable function. Are
those connected?
