use them in Postgres. These .tar.qz files seem to contain *.sql files.

Have you tried using the RETURNING function in your SQL insert statement
to immediately return the auto-generated key value? For example, how about

As far as I know it would be possible to include a manifest file (only

If its the OS cache the kernel ought to free the memory when there is
something else worth caching. Its not a big deal if the cache is full so
long as the system still performs well.

Then you'll have to build a query in plpgsql
From what i know, Aliases are literals, they are not variables, hence they
cannot be derived from something. you can derive them outside the scope of
normal SQL by using functions or shell scripts, but probably not inside an
