fix(s1,s2): handle PG17 pg_stat_statements column renames

In pg_stat_statements 1.11 (PG17), blk_read_time and blk_write_time
were renamed to shared_blk_read_time and shared_blk_write_time.

s1: use \if :postgres_dba_pgvers_17plus to select the right columns
s2: alias the new column names in the source CTE so all downstream
    references work without changes

Tested with shared_preload_libraries=pg_stat_statements on PG17.
All 30 queries now pass.
