Answer 2

根据hibernate docs

PostgreSQL81Dialect:    An SQL dialect for Postgres 
For discussion of BLOB support in Postgres, as of 8.4, have a peek at http://jdbc.postgresql.org/documentation/84/binary-data.html.

PostgreSQL82Dialect:    An SQL dialect for Postgres 8.2 and later, adds support for "if exists" when dropping tables

PostgreSQLDialect:  Deprecated. use PostgreSQL82Dialect instead

PostgreSQLDialect：已弃用。请改用

来使用PostgreSQL82Dialect
