From 8d9e025e7fcc68737d5a0e99b457417ed595af46 Mon Sep 17 00:00:00 2001
From: Tom Lane <tgl@sss.pgh.pa.us>

Subject: Instead of storing pg_statistic stavalues entries as text strings,
 store them as arrays of the internal datatype.  This requires treating the
 stavalues columns as 'anyarray' rather than 'text[]', which is not 100%
 kosher but seems to work fine for the purposes we need for pg_statistic.
 Perhaps in the future 'anyarray' will be allowed more generally.
