Could we make the PREPARE line read

PREPARE [ DEALLOCATE ] ...?

So it's more consistent, and the user using a PREPARE gets a clue to DEALLOCATE?


No. That is a syntax excerpt and the prepare command doesn't accept an optional deallocate keyword at that position.

If we wanted to improve the psql help here we'd have two options:
Add to the description:
prepare a statement for execution (undo this with Deallocate)

or teach our build system to add our "see also" section to the psql help pages.

The second seems reasonable but non-trivial.  The first just seems odd when reading the website.

There may be a third option but I actually haven't ever explored the psql help build module.
