PR Summary: Fix Resource Leak in performQuery Method

Overview

This PR addresses resource leaks in the performQuery method by implementing proper JDBC resource management using the Consumer pattern.

Changes Made

Core Enhancement:

• Modified AbstractContainerDatabaseTest.performQuery() method signature:
  • Before: protected ResultSet performQuery(JdbcDatabaseContainer<?> container, String sql) throws SQLException
  • After: protected void performQuery(JdbcDatabaseContainer<?> container, String sql, Consumer<ResultSet> consumer) throws SQLException
• Implemented try-with-resources pattern to ensure proper cleanup of Connection, Statement, and ResultSet objects
• Prevents resource leaks by guaranteeing JDBC resources are closed after query execution

Test Updates (20 files):
Updated all database module tests to use the new lambda-based pattern:

• ClickHouse (2 files)
• CockroachDB
• CrateDB
• Databend
• DB2
• MariaDB
• MS SQL Server
• MySQL (2 files)
• OceanBase
• Oracle (Free & XE)
• PostgreSQL (3 files including TimescaleDB & CompatibleImage)
• QuestDB
• TiDB
• Timeplus
• YugabyteDB

Pattern Applied:

// Old pattern (resource leak)
ResultSet resultSet = performQuery(container, "SELECT 1");
int value = resultSet.getInt(1);
assertThat(value).isEqualTo(1);

// New pattern (proper resource management)
performQuery(container, "SELECT 1", resultSet -> {
    Assertions.assertThatNoException().isThrownBy(() -> {
        int value = resultSet.getInt(1);
        assertThat(value).isEqualTo(1);
    });
});

Impact

• 21 files changed, 744 insertions(+), 251 deletions(-)
