Perhaps you want something like
regression=# \echo prompt
prompt
regression=# \set foo `read val; echo "'$val'"`
qwerty
regression=# select :foo;
?column?
----------
qwerty
(1 row)
although on the whole I think you'd be better off turning this around:
write it as a shell script and invoke psql for individual steps,
rather than the other way round. It's hard to envision a script that
needs user interaction and won't shortly thereafter need control
structures etc.
