This does belong in pgspecial package. We do have custom commands that are not DB commands in pgspecial. Take a look at the iocommands file in pgspecial. Also have a look at the develop.rst file, it talks a bit about how to add special commands. |

Here's a reference implementation from mycli: https://github.com/dbcli/mycli/blob/master/mycli/packages/special/iocommands.py#L165 |

psql has command \g | postgres=# explain select * from o obce obce_id_seq okresy postgres=# explain select * from obce limit 10 \g | wl-copy postgres=# There are lot of use cases - copy to clipboard is just one. |

@okbob, thanks for informing me about this. It is definitely very useful. But for my case it isn't enough. This is because I typically need the raw JSON format for pev2, and the output of to the clipboard. So unless there is some some |

So unless there is some some \pset option I don't know, then a more
fine-grained is required.
It is solved in psql 13, where you can use one shot parameters for \g
explain (format json) select * from pg_class limit 10 \g (format=unaligned

Description
When profiling Postgres queries with
EXPLAIN ANALYZE, it is often necessary to copy the query to the system clipboard in order to feed the output to a visualisation tool like (depesz)[explain.depesz.com].psqlhas no facilities for this, so I usually need to do something likeThis is annoying, so I see the advantage of a
\clipcommand that copies the DB output to the clipboard, which lets you doIt is different from the native DB commands, so I don't see how to implement it cleanly. It doesn't belong in
pgspecial. The present implementation is a bit ad hoc. It uses the packagepyperclip, which implements a cross-platform clipboard client.I am submitting this PR to solicit comments, with the hope to work toward a good solution. Please allow me to run workflows
