Those are third parties extensions, ES does clustering out of the box well. Most of the thing on your list don't have proper clustering solution built-in which means you have to support it yourself.
You said that PG had no clustering solutions, I showed you there were. Some of them may require more work than others but there ARE clustering options none the less for PG. It's inaccurate to say there are none.
PG doesn't even have a clustering solution out of Citus, how do you scale / HA postgres using the default setup without doing sharding yourself?
