Michael Paquier	76cbf7edb6	pg_stat_statements: Track I/O timing for temporary file blocks 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.

pg_stat_statements: Track I/O timing for temporary file blocks

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.

pg_stat_statements: Add some tests for older versions still usable

When the newest version is loaded, the backend would load objects from
the oldest complete SQL file (here 1.4) and then update to the latest
version with transition scripts (up to 1.9 currently).  This provides
some coverage for upgrades of pg_stat_statements, but there is no test
to show how things have changed across each version.

This adds a couple of tests for the upgrade paths using objects from
each version supported, stressing the objects whose behaviors have
changed across each version supported.
