Couldn't use clickhouse-jdbc 0.8.x with liquibase #2396

Description

I'm using liquibase version 4.32.0, when liquibase trying to parse clickhouse column meta data, it falls when parsing DATA_TYPE field. It expected to be Integer, and in 0.7.x versions it used to return as Int, but in 0.8.x version it just return String.

Steps to reproduce

1. Connect to Clickhouse using clickhouse-jdbc 0.8.x
2. Instantiate new Liquibase
3. liquibase.update

Expected Behaviour

Parsing correctly

Code Example

try (var connection = DriverManager.getConnection(url, info)) {
            connection.setAutoCommit(true);

            var database = new io.goodforgod.liquibase.extension.clickhouse.database.ClickHouseDatabase();
            database.setConnection(new JdbcConnection(connection));
            database.setDefaultCatalogName("default");
            database.setDefaultSchemaName("default");

            Liquibase liquibase = new Liquibase(
                    changeLogFile,
                    new ClassLoaderResourceAccessor(),
                    database
            );
            liquibase.update("");
        }
