Seth Fitzsimmons eb5dc746c2 [SPARK-28097][SQL] Map ByteType to SMALLINT for PostgresDialect ... ## What changes were proposed in this pull request? PostgreSQL doesn't have `TINYINT`, which would map directly, but `SMALLINT`s are sufficient for uni-directional translation. A side-effect of this fix is that `AggregatedDialect` is now usable with multiple dialects targeting `jdbc:postgresql`, as `PostgresDialect.getJDBCType` no longer throws (for which reason backporting this fix would be lovely): 1217996f15/sql/core/src/main/scala/org/apache/spark/sql/jdbc/AggregatedDialect.scala (L42) `dialects.flatMap` currently throws on the first attempt to get a JDBC type preventing subsequent dialects in the chain from providing an alternative. ## How was this patch tested? Unit tests. Closes #24845 from mojodna/postgres-byte-type-mapping. Authored-by: Seth Fitzsimmons <seth@mojodna.net> Signed-off-by: Dongjoon Hyun <dhyun@apple.com>		2019-07-17 15:10:01 -07:00
