Description:
I'm using radius authentication in pg_hba.conf and I've run into the
following issue.
The radiussecrets is always getting lowercased even if I start it with
double quotes. Seems the double quotes are removed by the tokenization
process and then the secret gets lowercased by
https://github.com/postgres/postgres/blob/REL_12_STABLE/src/backend/utils/adt/varlena.c#L3652
I'm attaching a patch for this since I don't think the secrets should ever
be lowercased.
