Re: Performance PLV8 vs PLPGSQL

[Michael Sheaver <msheaver@xxxxxx>]

If you want an IDE, Jetbrains, the makers of great IDEs like IntelliJ, PyCharm. and AppCode, among others, have recently come out with what is arguably the BEST IDE for DBAs, DataGrip. It runs on most major platforms, and is so good that I have bitten the bullet and paid the yearly subscription for it.

Leave the Postgres core alone focus on what they do best, and that is making the very BEST database environment that can be had at any price, period. Is Postgres perfect? No, not at all. But no other group is so focused on performance, scalability and security as these folks are. And the rate of development, enhancement and continual improvement is, quite honestly, astounding. 

So here is my hat tip to the Postgres team for an awesome job they are doing!

I am not saying the postgres core people should work on an IDE, just that an IDE like thing would be nice.

I would hope Postgres core folk take no more than a nanosecond to reject the idea that they work on an IDE. Focus on reading and writing faster and faster ACID all the while.

Honestly I don't even like JS. Having said that I am not too crazy about PL-PGSQL either. I am willing to put up with either given that they are supported widely in default installs of postgres in AWS, Linux and MacOSX,

As I said before, I think posgres gives a unique and underutilized language platform. You can code in different languages, it has a good variety of built in types, and of course you get persistance and caching built in!  Using DBLINK you might even be able to separate out your code from the bulk of your data in another database. Postgres all the way down!

It's fun to play around with.  There is a lot of missing pieces though. A good IDE like thing would be good, version control would be nice, deeper namespacing (hierarchical schemas?), easier testing etc would go a long way. 

Thanks for all the input guys!

    I think it's awesome that postgres allows you to code in different
    languages like this. It really is a unique development environment
    and one that is overlooked as a development platform.  It would be
    nice if more languages were delivered in the default package
    especially lua, V8 and mruby.


It is about dependencies and maintenance. There are not too much people
who has good experience with C embedding Lua, V8 and others. Any people
who can do some work are welcome.

The living outside main package has disadvantages - only enthusiast
knows about it, but some advantages too - you are not fixed on
PostgreSQL development cycle, and development can be faster.

I'll add my 2 cents.

Postgresql and in general SQL are about integrity and coherency.
Checking coherency is much easier with strict data type.
PL/PGSQL gives you that, JS is far far away from that.

Postgresql is a very flexible database and you can stretch it to do "MEAN like"[1] stuff but that's going to increase your "impedance mismatch".

If you think there is some space for JS in your application stack that's nearer to the client rather than to the DB.
Or possibly you need to do "MEAN like" stuff but you don't want to install another "database".

As other said using stored procedures is a two edged sword.
It can decouple DB schema from the application or it can increase the coupling.
Choosing JS for performance in the stored procedure realm is going to encourage coupling and make scalability harder and it is going to become a mess when you'll need to refactor.
