SUMMARY

Fills gaps in the default per-engine SQL function/table denylists and makes MySQL-derived engine specs pick up the MySQL defaults. These are defaults-completeness and cross-engine-consistency changes to superset/config.py; the lists remain fully operator-overridable.

• PostgreSQL DISALLOWED_SQL_FUNCTIONS: add the sequence functions setval, nextval, currval, lastval, next to the existing SELECT-callable state-changing entries.
• ClickHouse DISALLOWED_SQL_FUNCTIONS: add the table functions that read from locations outside the configured database — remote, remoteSecure, s3, s3Cluster, file, fileCluster, hdfs, mysql, postgresql, mongodb, jdbc, odbc — matching the external-data functions already covered for other engines. url was already listed.
• MariaDB coverage: the denylists are keyed by db_engine_spec.engine. MariaDBEngineSpec derives from MySQLEngineSpec but reports engine="mariadb", so it did not pick up the "mysql" entries. The MySQL function and table defaults are now mirrored onto "mariadb" — copied, not aliased, so overriding one engine's list in a deployment's config does not mutate the other's.

TESTING INSTRUCTIONS

Added unit tests:

• tests/unit_tests/config_test.py — the new PostgreSQL/ClickHouse defaults are present, and "mariadb" mirrors "mysql" for both dicts (equal but distinct objects).
• tests/unit_tests/db_engine_specs/test_mariadb.py — the db_engine_spec.engine lookup resolves the MySQL defaults for MariaDB.

pytest tests/unit_tests/config_test.py tests/unit_tests/db_engine_specs/test_mariadb.py
# 88 passed
