Subject: [PATCH 1/1] Rename "index_vacuum_count" to "index_vacuum_cycle_count"
 in in pg_stat_pogress_vacuum.

Commit 76d8a1bfd5207d28a4e9fe98a0e1ea7c096d70aa introduces 2 new columns
to track index vacuum/cleanup progress. The columns have "index" in the
name. To make it clear what the existing "index_vacuum_count" column
refers to, which is the cycle count of the index vacuum, this change
renames the column to "index_vacuum_count"
