Generic/Ad-Hoc Select Function

I am new to Postgresql and was wondering if it is possible to create an ad-hoc select query function, where the table name, and the where clause were passed to the function and it returned a result set for the table? 
 
Thanks

You can generate dynamic SELECT statements. See the docs at:

Yes. You should be able to do this in most of not all of the PLs. A good
start is to read this:
