This commit expands more the refactoring of the regression tests of
pg_stat_statements, with tests moved out of pg_stat_statements.sql into
separate files. The following file structure is now used:
- select is mostly the former pg_stat_statements.sql, renamed.
- dml for INSERT/UPDATE/DELETE and MERGE
- user_activity, to test role-level checks and stat resets.
- wal, to check the WAL generation after some queries.
Like e8dbdb1, there is no change in terms of code coverage or results,
and this finishes the split I was aiming for in these tests. Most of
the tests used "test" of "pgss_test" as names for the tables used, these
are renamed to less generic names.
