Fujii Masao 64ed30fda8 doc: Clarify COPY FROM WHERE expression restrictions ... Commit aa606b9316 disallowed generated columns in COPY FROM WHERE expressions, and commit 21c69dc73f disallowed system columns. However, the COPY reference page still mentions only the restriction on subqueries. Update the documentation to also list generated columns and system columns as unsupported in COPY FROM WHERE expressions. Backpatch the generated-column documentation change to all supported versions. Backpatch the system-column documentation change to v19, where that restriction was introduced.
