Commit: Jonas Bernoulli <jonas@bernoul.li>

    Update library commentaries of package libraries
    
    Some of these commentaries didn't take into account that these
    libraries are no longer included in the `emacsql' package, but
    are distributed as a separate packages.

 ;;; Commentary:
 
-;; Unlike emacsql-psql, this connection type uses Eric Marsden's pg.el
-;; to connect to PostgreSQL. It speaks directly to the database, so
-;; unlike the other EmacSQL connection types, this one requires no
-;; external command line programs.
+;; This package provides an EmacSQL back-end for PostgreSQL, which
+;; uses the `pg' package to directly speak to the database.
 
-;; The only pg functions required are pg:connect, pg:disconnect,
-;; pg:exec, and pg:result. Unfortunately, since pg.el is synchronous
-;; it will not be fully compliant once EmacSQL supports asynchronous
-;; queries. But, on the plus side, this means the implementation below
-;; is dead simple.
+;; (For an alternative back-end for PostgreSQL, see `emacsql-psql'.)
