Hello, as described in: http://www.postgresql-archive.org/Re-FEATURE-PATCH-pg-stat-statements-with-plans-v02-td6015488.html
I'm wondering about the best way to build a query planid. It seems natural (to me) to calculate a hash value based on the normalized plan text generated by explain (costs off, normalized) or maybe explain (costs off, verbose, normalized) this normalized output can be done by adding a modified get_const_expr in ruleutils.c as proposed in attached file. Would this "explain normalized" feature be interesting for core team and or users ?
