Advanced Server Dialect
EDB Postgres Advanced Server can be configured in one of two "Dialects" - 1) Compatible with Oracle or 2) Compatible with Postgres.
If you select Compatible with Oracle, Advanced Server will be configured with appropriate data type conversions, time and date formats, Oracle-styled operators, dictionary views and more. This makes it easier to migrate or write new applications that are more compatible with the Oracle database.
If you select Compatible with Postgres, Advanced Server will be configured with standard PostgeSQL data types, time/date formats and operators.
Advanced Server Dialect
[1] Compatible with Oracle
[2] Compatible with Postgres
Please choose an option [1] : 2
#这里是选择高级服务器可以配置两种方言（Dialects），我更熟悉PG一点，所以选择2

#安装完毕
配置环境
新建用户edb
为了方便使用和管理，我们新建edb用户来使用edb。
useradd -U edb
然后将安装好的安装目录和数据目录赋予用户权限
chown -R edb:edb /opt/edb/
chown -R edb:edb /sas_pgdata
配置环境变量
将新建的环境变量加到.bash_profile中
export PATH=/opt/edb/as10/bin:$PATH
export LD_LIBRARY_PATH=/opt/edb/as10/lib:$LD_LIBRARY_PATH
export PGDATA=/sas_pgdata
export PGHOST=/tmp
