Subject: remove unused shippability definitions from planner.h
X-Git-Tag: XL9_5_R1_4~47
X-Git-Url: http://git.postgresql.org/gitweb/static/gitweb.js?a=commitdiff_plain;h=5ce0e50ae7d3294fa7f66c7f35caed0ceb5f277c;p=postgres-xl.git

remove unused shippability definitions from planner.h

The ShippabilityStat type and shippability walker/test functions are not
really needed outside pgxcship.c.
