Fix #7627: The size of the database with big records becomes bigger after backup/restore
All checks were successful
continuous-integration/drone/push Build is passing

Browse Source 
The problem appears when bulk inserts are used (currently during restore). Without the fix the primary data page is released if it has the dpg_large flag, and the new record is inserted on the next empty page. As a result, each primary page has only one record. Generally the fix solves an issue where per-relation cache of data page numbers is not working for tables with big records.
