I think doing any sort of reasonable scripting around psql requires a 
reasonable shell.  Or next someone will suggest implementing loops and 
conditionals in psql.

For that matter, I suspect in any shell you can read the required 
variables beforehand and pass them into psql through arguments.  So the 
use case for reading variables during a psql script seems questionable 
anyway (without conditionals, at least).
