Yes, good thought.

It would be useful to have some way to express dependency there, rather
than just sequence.

search_path_add = 'my_module1, my_module2'
search_path_depends = 'postgis'

So that we can assemble a search_path with final sequence based upon the
dependency tree, rather than risk a weird sequence.

We might need to have a special keyword in the main search_path to show
where additions go, e.g.
search_path = '$user, $install, public, pg_catalog'

This is beginning to sound like a very workable mechanism for plugins.
