This changes the data type of the catalog fields datcollate, datctype, collcollate, and collctype from name to text. There wasn't ever a really good reason for them to be of type name; presumably this was just carried over from when they were fixed-size fields in pg_control, first into the corresponding pg_database fields, and then to pg_collation. The values are not identifiers or object names, and we don't ever look them up that way. Changing to type text saves space in the typical case, since locale names are typically only a few bytes long. But it is also possible that an ICU locale name with several customization options appended could be longer than 63 bytes, so this also enables that case, which was previously probably broken.
