Add WRITE_INDEX_ARRAY
We have a few WRITE_{name of type}_ARRAY macros, but the one caseusing the Index type was hand-coded. Wrap it into a macro as well.This also changes the behavior slightly: Before, the field name wasskipped if the length was zero. Now it prints the field name even inthat case. This is more consistent with how other array fields arehandled.Reviewed-by: Jacob Champion <pchampion@vmware.com>Discussion:https://www.postgresql.org/message-id/c091e5cd-45f8-69ee-6a9b-de86912cc7e7@enterprisedb.com
