Purpose
Speed up item barcode right truncation searches.
The index for item barcode right truncation will be used by checkin and checkout:
https://github.com/folio-org/ui-checkout/blob/v11.0.0/src/ScanItems.js#L163-L164
https://github.com/folio-org/ui-checkin/blob/v9.2.0/src/Scan.js#L318-L319
The existing btree index doesn’t support right truncation because barcode is Unicode and not "C" locale, for details see
https://www.postgresql.org/docs/current/indexes-opclass.html
https://www.cybertec-postgresql.com/en/indexing-like-postgresql-oracle/
Approach
Add a text_pattern_ops index for item barcode.
