Here we are.
Please find attached a rebased version and while at it, v2 adds a new macro and
a function to avoid some code duplication between pg_buffercache_pages() and
pg_buffercache_numa_pages().
So, PFA:
0001 - Introduce GET_MAX_BUFFER_ENTRIES and get_buffer_page_boundaries
Those new macro and function are extracted from pg_buffercache_numa_pages() and
pg_buffercache_numa_pages() makes use of them.
0002 - Add os_page_num to pg_buffercache
Making use of the new macro and function from 0001.
As it's for v19, also bumping pg_buffercache's version to 1.7.
