ThanoshanMV opened a new pull request, #18272: URL: https://github.com/apache/shardingsphere/pull/18272
For #17844 Changes proposed in this pull request: - Added PostgreSQL [Copy Statement](https://www.postgresql.org/docs/current/sql-copy.html). - Added test cases. - Added `E?` in `STRING_` to represent the [escape string constants](https://www.postgresql.org/docs/current/sql-syntax-lexical.html#SQL-BACKSLASH-TABLE) specified by writing the letter E just before the opening quote. For example, `E'foo'`. This is added to support queries like `COPY t_order FROM STDIN WITH NULL AS E'\\0';`. - Omitted `copy_by_postgresql_source_test_case3` as it is not aligned.  In the above query, `[ NULL [ AS ] 'null_string' ]` cannot be followed with `ENCODING 'encoding_name'` as there is no definition of `ENCODING` there.  - Modified `copy_by_postgresql_source_test_case5` as `copy_table_to_stdout_with_csv_force_quote`, `ESCAPE E'\'` must come before `FORCE QUOTE col2;`  Please let me know if there is anything to change. -- This is an automated message from the Apache Git Service.
