bug bush: postgres table definition schema

[kyoto7250]

The way to easily check table schema in postgres was different from MySQL.
We will consider how to resolve this, or consider turning off the behavior in Postgres.

This needs to be resolved by July 7th, so it is an issue that should be considered within that time frame.
