…r maintainer review (OtterMind#1914) - new RedshiftIdentifierProcessor (SPI ISQLIdentifierProcessor): quoteIdentifier with double-quote doubling, escapeString with single-quote doubling - RedshiftMetaData overrides getSQLIdentifierProcessor(); SHOW CREATE TABLE call site uses RedshiftIdentifierProcessor.INSTANCE - RedshiftSqlEscapes removed; tests migrated (9 green)
…uote for DDL paths (OtterMind#1914) - quoteIdentifier(String) is conditional again: null/blank passthrough, valid plain identifiers returned unquoted, otherwise wrapped with double quotes after stripping one pair and doubling embedded quotes - new quoteIdentifierAlways(String) for DDL-generation sites; buildShowCreateTableSql uses it (was RedshiftSqlEscapes.quoteIdentifier) - quoteIdentifierIgnoreCase keeps the always-quote SPI variant meaning; versioned overload delegates to quoteIdentifier(String) - tests cover both conditional and always behaviors incl. null passthrough

Part of the SQL-injection hardening tracked in #1914. Prior art: #2052 (Oracle), #2053 (SQL Server), and the wave-1 batch (#2172-#2177).
These are second-order injection paths: values such as table/schema/view/index names originate from the connected database's own metadata, so exploitation requires a maliciously named object in a target database.

RedshiftMetaData tableDDL/viewDDL identifier paths now quoted+escaped via new RedshiftSqlEscapes.

This branch also passed a two-lens adversarial review (escape-correctness/coverage + regression/test-efficacy); all blocking findings were fixed and re-tested before submission.
