Coverage of the query jumbling code has always relied on the queries included in the regression tests of pg_stat_statements. This has its limitations, as a lot of query patterns have never really stressed the query jumbling code. The situation got a bit worse since the query jumbling has been added in the backend core code (5fd9dfa), hence new nodes that should be included in the jumbling could easily be missed, resulting in failures in pg_stat_statements or any modules that require query ID computations. Forcing a load of pg_stat_statements in 027_stream_regress.pl ensures that nodes are never missed in the computations, without having to rely on a buildfarm member for this check. Before this commit, the line coverage of queryjumblefuncs.funcs.c was around 48.5%, now up to 94.6% just by running 027_stream_regress.pl. A basic check is added to show that pg_stat_statements reports are generated after the main regression test suite is finished. Discussion: https://postgr.es/m/Y+nD9LN70w+8eaG9@paquier.xyz
