I have seen various links on the internet which indicate that PLV8 is significantly faster than PL-PGSQL sometimes an order of magnitude faster.
Is this uniformly true or is it just in certain circumstances?
Is there any benefit to choosing PL-PGSQL?
Is there work going on to make PL-PGSQL more performant or has it gotten significantly faster in the last two years or so (some of the links are a from a while ago).
Thanks.
