We must update gorm

User Case Description

Gorm must be upgraded, current v1.5.5 is not compatible.

It makes more sense to remove the tag.

Wait for the Gorm upgrade to complete, and then re-upgrade the postgres driver.

If we decide to do so, we can close this mr.

gorm dependency to driver is ok , driver dependency to gorm(except interface) is not best, choice,should we consider it more?

gorm dependency to driver is ok ,but the implementation of driver dependency to gorm is not best, choice,should we consider it more?

I agree, but it seems that #195 must depends on go-gorm/gorm#6386, that's a breaking change, just like go-gorm/mysql#123.

But I foolishly forgot to remind jinzhu about this.

I've deleted tag v1.5.5.
Next we need to discuss rollback, or how to fix it.
