Subject: Hide list of nodes in EXPLAIN (NODES off, FORMAT json)
X-Git-Tag: XL_10_R1BETA1~289
X-Git-Url: http://git.postgresql.org/gitweb/static/gitweb.js?a=commitdiff_plain;h=dfbb88e3bbb526dcb204b456b9e5cfd9d10d0d0a;p=postgres-xl.git

Hide list of nodes in EXPLAIN (NODES off, FORMAT json)

EXPLAIN with json format was ignoring the NODES option, showing the list
of nodes every time. This commit fixes that.
