Minimal psql tab completion support for SET search_path.

anarazel · anarazel · commit bd409519bd19 · 2014-07-12T15:44:39.000+02:00
Complete SET search_path = ... to non-temporary and non-toast
schemas. Since there pretty much is no use case to add those to the
search path and there can be many it's helpful to exclude them.

It'd be nicer to complete multiple search path elements, but that's
not easy.
