Hi, thanks both for the reply.
> The description for pg_index.indkey uses the phrasing “an expression over the table columns” and this should be made to match.
Thanks David for showing me that existing documentation, I agree we should make them match.
Regarding Tom’s reply, IMHO, “LOWER(last_name || ' ' || first_name)” is still an expression over table columns? Would you like to elaborate on it a bit?
Regards, Steve.
