What changes are proposed in this pull request, and why are they necessary?
This PR reverts #460 due to its failure to remove CHARACTER SET from the Trino SQL in some production views. This caused the translated Trino SQL to become unparsable. Reverting it has resolved the issue. We intend to revert it in the Trino hotfix branch and revisit it later.
