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.
