Thanks! Yes, I missed the Meson build file. I added additional
commands with EXPLAIN (COSTS OFF) as I found in other places.

Patch updated for those comments (and a touch of cleanup in the tests) attached.

Commits

  1. Add hash support functions and hash opclass for contrib/ltree.

  2. Add ALTER OPERATOR command, for changing selectivity estimator functions.
