New file: Open-ILS/src/sql/Pg/upgrade/XXXX.data.monograph_parts_grid.sql

Don't worry about trying to predict what the next sequential script number will be, just use "XXXX" and the core committer will update it at commit time.

BEGIN;

-- SELECT evergreen.upgrade_deps_block_check('XXXX', :eg_version);

INSERT into config.workstation_setting_type (name, grp, datatype, label)
VALUES (
    'eg.grid.catalog.record.parts', 'gui', 'object',

        'Grid Config: catalog.record.parts',
        'cwst', 'label'
       )
