## Problem

Build index concurrently is writing WAL outside transaction.
`backpressure_throttling_impl` doesn't perform throttling for read-only
transactions (not assigned XID).
It cause huge write lag which can cause large delay of accessing the
table.

## Summary of changes

Looks at `PROC_IN_SAFE_IC` in process state set during concurrent index
build.
