Understand and modify the COPY FROM / COPY TO family in PostgreSQL — src/backend/commands/copy.c. Loads when the user asks about COPY-command internals, bulk-load performance, custom COPY formats, extending COPY options, COPY error-handling / ONERROR, COPY progress reporting, tablesync (which is built on COPY), or any patch touching copy.c / copyfrom.c / copyfromparse.c / copyto.c. Also use when investigating why COPY behaves differently from INSERT (partition routing, defaults, generated columns, extended statistics, RLS, triggers, DEFAULT expressions), and when adding a new bulk-load code path that reuses the COPY machinery. Skip when the question is about pgdump / psql \copy (client-side) or logical-replication apply (different subsystem — but note that tablesync's initial copy IS this machinery, see knowledge/idioms/tablesync-initial-copy.md).

Quick start
Copy the install prompt. Use the green button above this README.
Send it to your agent. Paste it into your coding agent’s chat and send.
Review the setup. Your agent checks the skill’s instructions, requirements, and installation scope.
Understand and modify the COPY FROM / COPY TO family in PostgreSQL — `src/backend/commands/copy*.c`. Loads when the user asks about COPY-command internals, bulk-load performance, custom COPY formats, extending COPY options, COPY error-handling / ON_ERROR, COPY progress reporting, tablesync (which is built on COPY), or any patch touching `copy.c` / `copyfrom.c` / `copyfromparse.c` / `copyto.c`. Also use when investigating why COPY behaves differently from INSERT (partition routing, defaults, generated columns, extended statistics, RLS, triggers, DEFAULT expressions), and when adding a new bulk-load code path that reuses the COPY machinery. Skip when the question is about `pg_dump` / `psql \copy` (client-side) or logical-replication apply (different subsystem — but note that tablesync's initial copy IS this machinery, see `knowledge/idioms/tablesync-initial-copy.md`).
