Alternatively - we could add the column index as a field in JdbcFieldInfo so that signatures do not have to change

Thank you for review @lidavidm
JdbcFieldInfo with additional column index is works for me

…ils (apache#14134) This pull request allows support of mapping for map type (hstore translated by jdbc driver to java.util.Map or json text/varchar). Mapping for MapConsumer should be manually expressed in new JdbcToArrowConfigBuilder(...).setJdbcToArrowTypeConverter(USER_CUSTOM_jdbcToArrowTypeConverter). Now it possible as part of [ARROW-17630](https://issues.apache.org/jira/browse/ARROW-17630) that allow user to distinguish columns by number and related external metadata.
