   I want to convert into Apache Arrow IPC data format in Java existing data 
from PostgreSQL database.
   
   
[JdbcToArrowUtils.jdbcToArrowSchema](https://github.com/apache/arrow/blob/50a7d15dfb4cbc4dd449ff2bb3ba2b1cde62a3ab/java/adapter/jdbc/src/main/java/org/apache/arrow/adapter/jdbc/JdbcToArrowUtils.java#L111)
 allows do it for scalar types and arrays.
   
   org.postgresql.jdbc.PgResultSetMetaData instance from PostgreSQL jdbc driver 
provide all required info related to column types 
pgResultSetMetaData.getColumnTypeName(). 
   
   But looks like current implementation support only [ArrowType.List](
   
https://github.com/apache/arrow/blob/50a7d15dfb4cbc4dd449ff2bb3ba2b1cde62a3ab/java/adapter/jdbc/src/main/java/org/apache/arrow/adapter/jdbc/JdbcToArrowUtils.java#L266
 
   )  with no support of Map type mapping in code
   
   How to get Apache Arrow schema and transform data into Arrow for hstore(map) 
and geometry database column types?
