Using result from current_database() into another command?

[Francisco Reyes <lists(at)stringsutils(dot)com>]

select current_database();
current_database

Is there a way to use that result from current_database() into something 
like: 
alter database CURRENT_DATABASE() set search_path=myschema,public;

I have some generic scripts that I am preparing for several databases. Most 
commands/loads don't care about the database, since they just use the one I 
am connected to. Alter database however needs the database specified.
