Can I alter a table column to now make it generated? I tried this

alter table tmp1 alter column avgspd type numeric(7,3) generated always
as ((3600.*distance)/EXTRACT (EPOCH FROM rdrtime::interval)) STORED;
ERROR: syntax error at or near "generated"
LINE 1: ... table tmp1 alter column avgspd type numeric(7,3) generated ...

See David Johnston's comment. I keep on wanting to believe that ALTER
TABLE supports GENERATED expressions, when it only supports GENERATED
IDENTITY:)
