Dont mix frontend and backend in your approach.
You can specify variables in whatever way your
stored function handles it (e.g. it depends on
the language you use. Examples for pl/pgsql
are in the docs.)
In Postgres you dont write arbitrary code
to the server. You write stored functions
(server side) or you write SQL statements.

Any further variable handling is up to your
host/application language.

psql, the command line client application
does not have variables as such nor any
flow control.
