Upgrade note about postgres connections

Diana Stanley requested to merge master-patch-9c18 into master

What does this MR do and why?

In GitLab 16.0 we have added a second database connection that effectively doubles the maximum postgres connections used by the system. The impact of this is not well called out to customers, and we've started seeing tickets from customers after upgrading to 16.x. This is an attempt to put the notice in our upgrade documentation with a pointer to the postgres docs that describe what's going on, why, the possible impact, and remediation steps.
