Remove redundant check for default collation.

jeff-davis · jeff-davis · commit 6a9fc11033e6 · 2024-09-12T13:35:49.000-07:00
The operative check is for a deterministic collation, so the check for DEFAULT_COLLATION is redundant. Furthermore, it will be wrong if we ever support a non-deterministic default collation. Author: Andreas Karlsson Discussion: https://postgr.es/m/60929555-4709-40a7-b136-bcb44cff5a3c@proxel.se
