   Thanks @cloud-fan. The write path is intended to keep the existing 
not-selectable behavior: existence checks treat the object as absent, so V1 
`DataFrameWriter.jdbc` and catalog `CREATE TABLE IF NOT EXISTS` / CTAS proceed 
to `CREATE TABLE` instead of failing with ORA-00980. An unqualified public 
synonym creates a local table that shadows it; a private synonym still fails at 
CREATE with ORA-00955. That is the same as ORA-04044 / ORA-04063 since 
SPARK-57778. I updated the user-facing section of the PR description to say so.
