"""
SAP HANA dialect.

HANA has no first-party sqlglot dialect, so Superset maps it to Postgres.
Postgres normalizes function-call names to uppercase on generation
(``NORMALIZE_FUNCTIONS = "upper"``). HANA calculation-view invocations are
addressed as a quoted, case-sensitive identifier followed by a PLACEHOLDER
parameter list, e.g. ``"zbw.10_001/INVENTORY"('PLACEHOLDER' = (...))`` --
sqlglot parses that shape as a function call, so the inherited
normalization silently re-cases the quoted identifier to
``"ZBW.10_001/INVENTORY"``. HANA resolves calculation-view names
case-sensitively, so the re-cased identifier no longer exists and the
query fails at execution time.
