I wanted to add a char array with length of 20 to PageHeaderData in include/storage/bufpage.h.
Surprisingly regression test failed on rangetypes test!
The diff of resulted and expected file is :
*** 968,974 **** select count(*) from test_range_spgist where ir -|- int4range(100,500); count ------- ! 5 (1 row)
-- now check same queries using a bulk-loaded index --- 968,974 ---- select count(*) from test_range_spgist where ir -|- int4range(100,500); count ------- ! 2 (1 row)
-- now check same queries using a bulk-loaded index
