+** Postgres with pgvector
+The popular database Postgres has an extention that allows it to have vector
database functionality, [[https://github.com/pgvector/pgvector][pgvector]].
This needs the =pg-el= library.
+
+A provider defines a database, and the collection will define a table with the
collection name in that database.
+
+For example,
+#+begin_src emacs-lisp
+(defvar my-postgres-provider (make-vecdb-psql :dbname "mydatabase" :username
"myuser"))
+#+end_src
+
+This also takes an optional password as well. For now, this just uses
localhost as a default.
