Prompt for parameter value in psql

Hi,
Would it be possible to prompt for a user input in psql like in Oracle sqlplus?

In oracle, we use the & sign, for example,
select * from emp where empid=&empidvalue;

Thanks.

\prompt [ text ] name

Prompts the user to supply text, which is assigned to the variable name. An optional prompt string, text, can be specified. (For multiword prompts, surround the text with single quotes.)

By default, \prompt uses the terminal for input and output. However, if the -f command line switch was used, \prompt uses standard input and standard output.
