Обсуждение: [HACKERS] CREATE COLLATION IF NOT EXISTS

Here is a patch to complete the implementation of CREATE COLLATION IF
NOT EXISTS.  The meat of this was already implemented for
pg_import_system_collations; this just exposes it in the SQL command.

If we go ahead with ICU, then creating collations by hand will become
more common, so this could be useful in practice.
