Fix handling of collations in multi-row VALUES constructs.
Per spec we ought to apply select_common_collation() across the expressions in each column of the VALUES table. The original coding was just taking the first row and assuming it was representative. This patch adds a field to struct RangeTblEntry to carry the resolved collations, so initdb is forced for changes in stored rule representation.
