We have discovered issues that prevent shifting the datatracker to 
postgresql on 19Jan.

These will take long enough to remedy that we will be in the active 
pre-IETF 116 period by the time we are ready, so we are rescheduling the 
shift until after that meeting.

This outage is now scheduled for Tuesday 11Apr2023 just after 21:00 UTC.

The essence of the issue is in the different collation between MySQL and 
Postgresql. Our initial tests indicated that we were safe proceeding to 
Postgresql's case-sensitive collation with the code changes we've 
already made, but more detailed work in December and early January have 
shown that more are necessary.
