How can I transform the following definition to index pubyear as
integer and not text?
CREATE INDEX pubyear_idx
ON some_table_where_data_field_is_of_type_jsonb USING btree
((((((data -> 'REC'::text) -> 'static_data'::text) ->
'summary'::text) -> 'pub_info'::text) ->> '@pubyear'::text) COLLATE
pg_catalog."default");
While I can cast the value in a SELECT statement to integer I have
been able to do the same while creating the index.
Why btree index? I want to do queries like
select stuff from sometable where pubyear between 2015 and 2018;
Regards
Johann
