All those OR conditions on different tables and fields seems like it will be unlikely that the planner will do anything with the index you are trying to create (for this query).
On the error, I came across discussions on
dba.stackexchange.com referencing a limit of about 1/3 of the page size (8192) for every key because of it being a btree underneath. It could be one or more of your keys in ops (like shop, camp_code, and shipping_company) is much longer than those examples shown in the query.
