This commit adds two new columns to pg_stat_statements, called
temp_blk_read_time and temp_blk_write_time. Those columns respectively
show the time spent to read and write temporary file blocks on disk,
whose tracking has been added in efb0ef9. This information is
available when track_io_timing is enabled, like blk_read_time and
blk_write_time.
pg_stat_statements is updated to version to 1.10 as an effect of the
newly-added columns. Tests for the upgrade path 1.9->1.10 are added.
PGSS_FILE_HEADER is bumped for the new stats file format.
