I'm just going to say one thing about that: some people will remember
that you can build a Turing machine with either conditionals+iteration
or conditionals+recursion. I wonder what depth of include-file nesting
psql can support, or whether we'll be able to fix it to optimize tail
recursion of an include file. Because somebody will be asking for that
if this is the toolset you give them.

PS: if I'm being too obscure for you, consider:
$ cat loop.sql
\if :x < 1000
\set x :x + 1
$ psql --set x=0 -f loop.sql
Somebody is going to think of that workaround for not having loops, and
then whine about how psql runs out of file descriptors and/or stack.
