Add missing connection statuses to docs
The list of connection statuses that PQstatus might return during anasynchronous connection attempt was outdated:1. CONNECTION_SETENV is never returned anymore and is only part of the enum for backwards compatibility, so remove it from the docs.2. CONNECTION_CHECK_STANDBY and CONNECTION_GSS_STARTUP were not listed, so add them.CONNECTION_NEEDED and CONNECTION_CHECK_TARGET are not listed in the docson purpose, since these are internal states that can never be observedby a caller of PQstatus.Author: Jelte Fennema-Nio <postgres@jeltef.nl>Discussion:https://postgr.es/m/CAGECzQRb21spiiykQ48rzz8w+Hcykz+mB2_hxR65D9Qk6nnw=w@mail.gmail.com
