TBH I do not see this happening. GET DIAGNOSTICS is just the tip of the
iceberg. The SQL standard uses "=" for assignment in other contexts,
most notably UPDATE, but also the SQL/PSM standard uses it in
<assignment statement> which is the exact same thing as in pl/pgsql.
So while purists might wish we only accepted :=, doing so would be
inconsistent with SQL.
I think we should just document it and move on.
