We roll onto new stuff. So soon-ish the 11 will be replaced with a 14 or 15. And then later the 13 will roll up to whatever is good, stable and tested in our environment. And our roll-up plan has never seen an old PG lose client library access. PG has never ever, in 20+ years been the thing that holds us back. I also think risk-management has many more (important) factors than EOL. Edit: quick check shows we also have PG9 and PG10 in some Live roles too.
