Feature/tibero connector

[thehkkim]

Description

This PR adds a new JDBC connector for Tibero database. Tibero is an enterprise-grade relational database management system that is Oracle-compatible and widely used in enterprise environments.

The connector extends BaseJdbcClient and provides:

• Support for common SQL data types (numeric, character, timestamp, binary)
• Tibero-specific type mappings for DATE and TIMESTAMP types with precision up to 9
• Proper handling of B.C. dates (year adjustment)
• Type conversion handling for CLOB, NCLOB, BLOB, and RAW types

Additional context and related issues

The implementation follows the same pattern as other JDBC connectors in Trino (e.g., Oracle, PostgreSQL). The connector handles Tibero's type system including:

• Numeric types: SMALLINT, INTEGER, BIGINT, REAL, DOUBLE, DECIMAL/NUMERIC
• Character types: CHAR, VARCHAR, NVARCHAR, CLOB, NCLOB
• Binary types: VARBINARY (RAW), BLOB
• Temporal types: DATE, TIMESTAMP with nanosecond precision

Note: The connector uses a system-scoped JDBC driver dependency which needs to be configured with the actual Tibero JDBC driver location.

Could you add the connector tests?

Please add type mapping tests, you can refer TestPostgreSqlTypeMapping

does the jdbc allows using in open source project, what's the license it allows?

[chenjian2664]

Could you please add a link to the database's official homepage? I’m not familiar with it, and having a reference link would help readers understand it better
