System columns appeared when using data transfer

### Description

When I use data transfer to import a csv in an existing table, on the "target" columns, the system columns are appearing (tableoid, cmax, xmax, cmin, xmin, ctid).
This didn't occur in version 22, so it must be a relatively recent change.
This is an unwanted change, nobody wants to import into system columns. Or make it a preference that can be turned off.

### DBeaver Version

Community Edition Version 24.0.0.202403031740

### Operating System

_No response_

### Database and driver

Postgresql 12

### Steps to reproduce

_No response_

### Additional context

_No response_

Start by reproducing the issue in DBeaver Community 24.0.0 with PostgreSQL 12 using the data transfer CSV import into an existing table. Trace how the target columns are populated and compare the result with version 22. Done means system columns such as tableoid, cmax, xmax, cmin, xmin, and ctid no longer appear as import targets, or can be disabled by a preference.
