Nope.

Extensive support for a variety of variable types and constructions is
available in FUNCTIONS. PL/pgSQL, PL/TCL, PL/Perl ... take your pick.

For the raw command-line SQL, variables, constants, and other procedural
language elements are not appropriate. This is best done in procedures,
functions, and middleware.

Of course, it is an Open-Source project, so if you hire your own
programmer, you can do anything you want.
