Polyglot means not having to fight with marshaling overheads when integrating bespoke compute functions into SQL, or when producing input to / consuming the output from queries. This could radically change the way in which non-expert people construct complex queries and efficiently push more logic into the database layer, and open the door to bypassing SQL as the main interface to the DBMS altogether.
Vector processing means improved mechanical sympathy. Even for OLTP the row-at-a-time execution model of Postgres is leaving a decent chunk of performance on the table because it doesn't align with how CPU & memory architectures have evolved.
