> There is a table about 1000K+ record
> Postgresql Version: server 9.2.7

> The table definition:

> 1. When I make this table available in Mysql, and select * from it in Teiid, It will quickly get the data stream after around 30s.
> 2. But when I make this table in Postgresql DB, and query through Teiid, it is so slow and will get about 8min+ client can not get the data stream,
> when I try to directly connect this table in Postgresql table, it is much more faster, I do not know the reason.
