Comments:

For PostgreSQL, depending on the table definition, the required pseudo column (oid) on a positioned UPDATE or DELETE might be missing.

For MySQL, depending on the table definition, the required pseudo column (_rowid) on a positioned UPDATE or DELETE might be missing.

If positioned UPDATEs and DELETEs are required, you might need to change your PostgreSQL or MySQL table definition to expose the appropriate pseudo column and make it available.

When positioned UPDATEs and DELETEs are not required, use NOWHERECURRENT.
